Coordinates Interview by Dr Jayanta Kumar Ray

Your vision is “Innovative Information Technology Solutions for a better world”. Explain how your products and solutions are aligned with the vision statement.

Accord has been striving to create innovative technology solutions that benefit our customers in particular and the nation at large over the past two and a half decades. By virtue of steady and continuous investments in research and development into Global Navigation Satellite System (GNSS) and allied fields, Accord has provided out-of-thebox techniques and methods to solve the customer needs in many critical applications including automotive, defence, and aerospace. Some of our key customers such as Research Centre Imarat (RCI-DRDO) and Indian Space Research Organization (ISRO) always encouraged us to create Indigenously Designed Developed and Manufactured (IDDM) GNSS receivers that motivated us to build innovative solutions.

We believe Accord played a key role in our country achieving self-reliance in navigation area in aerospace and defence. Our vision was truly rewarded when we received DRDO Technology Absorption Award from the Honorable Prime Minister of India Sri Narendra Modi for the indigenous design, development and production of Advanced High Dynamics GPS+GLONASS+GAGAN Receivers.

Accord has been one of the leaders in developing SBAS receivers. How has been its penetration among users so far?

Accord built the first GPS-SBAS receiver in 2005 and got it certified by the Federal Aviation Administration (FAA) of the United States for airworthiness in 2007. Since then, Accord has created nearly half-a-dozen variants of the GPS-SBAS receiver and got them certified by the FAA. These safety-critical and lifecritical GNSS receivers guarantee to have better than one-in-ten-million failure rate. Accord’s GPS-SBAS receivers are used in thousands of general aviation aircraft, experimental aircraft, UAVs, drones etc. in the USA, UK, Australia, Italy, Germany, Israel and other countries. Some of the aircraft models where our GPS-SBAS receivers are used are Beechcraft, Cessna, Dornier, Pilatus, Piper and Bell Helicopter. This is one Indian product which has gone truly global. In India, our FAA certified GPS-SBAS receivers were used in GAGAN signalin- space validation. Variants of the GPSSBAS receivers, including GPS-SBASGLONASS and IRNSS-GPS-SBASGLONASS receivers are used in many critical applications in India including automotive, helicopter, aircraft, UAVs, ships, smart bombs and many other platforms for navigation and guidance.

What has been the best “time to first fix” by Accord GNSS receivers?

The ‘time-to-first-fix’ of Accord’s GNSS receivers are amongst the best in the world. Accord’s GNSS receivers are benchmarked with the best in class GNSS receivers in the world in terms of cold start time, warm start time, hot start time, signal reacquisition time in open sky, low signal and obstructed view conditions and found to be at par.

How ready Accord is, for handling Dual frequency multi-channel capability?

Accord not only has the capability of dual frequency multi-channel GNSS receiver, but, we already have ready solution of dual frequency, multi-constellation, multichannel GNSS receiver. Accord developed IRNSS dual frequency Reference receiver for ISRO in 2013 even before the IRNSS satellites were launched. Today, Accord has multi-constellation GNSS receivers covering GPS L1, L2, L5, GAGAN L1, GLONASS L1, L2, Galileo E1, E5a, E5b, IRNSS L5, S, BeiDou B1, B2 constellation receivers.

How do you see the growth potential of GAGAN in India?

GAGAN provides integrity information in addition to the corrections to the satellites measurements. GNSS receivers employ information from GAGAN to enhance the integrity and reliability of the position solution and compute the error protection limits, suitable for aviation applications. Further, GAGAN enhances the accuracy and availability of GPS solution. Position information with high degree of reliability and accuracy from GPS-GAGAN is also very useful for safety applications including aerospace, railways, mining, precision farming, precise timing and automotive applications. Additionally, the text messaging services from GAGAN could be very effectively used for disaster management.

What is your opinion to explore the potential synergy between IRNSS and GAGAN?

IRNSS and GAGAN have very different objectives. While, IRNSS provides an independent means of position computation using Indian satellite navigation system, GAGAN is used to improve the reliability and accuracy of the computed position using US GPS. IRNSS by virtue of its dual frequency satellite signals at L5 and S, allows the receiver to have ionospheric-free measurements. On the contrary, GAGAN satellite signal provides estimates of the ionospheric errors to single frequency GPS receivers. It is conceivable that IRNSS and GAGAN satellites send corrections to measurements that would benefit the single frequency GPS-GAGAN and GPS-IRNSS receivers.

Do you think that India is ready to use IRNSS as we use GNSS in our daily life?

Today, GPS is used in all walks of life and has become integral part of our dayto- day life. For example, it is extensively used for route guidance, fleet operations, asset tracking etc. It is expected that in the coming days many of these operations will be carried out using IRNSS, in addition to GPS. However, this could happen only when inclusion of IRNSS does not drive the cost of the system substantially. That means someone must come out with IRNSS chipset solution soon, which could bring down the cost to own IRNSS receiver. A mandate from the Government recommending use of IRNSS in critical applications could make IRNSS popular in India.

What are key challenges faced by companies like Accord to develop technologies pertaining to GNSS for India and overseas?

Accord has been developing GNSS receiver solutions for Indian and overseas customers for more than two decades. Accord’s receiver solutions are used in space, military aerospace, civilian aircraft, automotive, hand-held, timing and varieties of applications. The major challenges faced by companies like Accord are a) most often the selection of a receiver by the end-user is governed by the cost alone and not by its feature, indigenousness, technical support and after-sale service b) some of the tax structures are not favorable to indigenous product development c) Quantities required in India are small compared to the world market, therefore, it is difficult to make big investment for Indian market only and d) very few educational institutes teach GPS technology and therefore there is always a shortage of trained manpower to work in the development of GNSS receiver.

How do you see the private sector contribution in technology research and role in growth of GNSS technology based market in India?

GNSS technology is of strategic importance to the country and has a big role to play in the economy of the country as well. The investment made by US in GPS enabled a trillion-dollar economy spanning multiple sectors such as Aviation, Automobiles, logistics, Timing, Security and Mobile navigation. While companies like Accord is focusing on research in the core GNSS area, there are several players developing application based on them. Fleet tracking and Asset Tracking are the two critical applications areas which can deeply impact the everyday life of all Indians in the years to come.

What initiatives should be taken by private sector in engaging with educational institutions for improving GNSS technology research?

First we need to create awareness of the huge opportunity offered by Navigation to all the students. The kind of applications one can make using this technology is only limited by one’s imagination only. Towards this Private sector companies like us should conduct workshops in colleges and offer products at a discount to the student community. We also need to sponsor good students for higher studies in the area of navigation or provide internship opportunities at our workplace.

Tech in place to source data from desi GPS

BENGALURU: The launch of seven satellites under the Indian Regional Navigation Satellite System (IRNSS) by the Indian Space Research Organisation (Isro) saw the dream of an Indian Global Positioning System coming true. Now, data from the constellation is ready to be sourced by indigenous systems, which will take it to millions of Indians through a variety of applications.

From alerting fishermen about the weather to aiding security agencies in surveillance, data from IRNSS can be used in a wide range of applications in science, aviation and financial services, among others. However, it will be some time before the new technology replaces the existing GPS on our smartphones as it requires changes to hardware specifications.

The Bengaluru-based Accord Software and Systems Private Limited has been developing GPS-based technology for the past two decades. The company has now developed three systems that can utilise data from IRNSS. “We're ready with three systems that people and organisations can directly buy and use. We also possess the knowledge to design chipsets just like the ones used to source GPS data, that can be used on mobile phones to provide information on positioning, etc.We're currently in talks with a few Indian handset manufacturers,“ said Accord vice president (India business development), Varadraj GS.

J K Ray of Accord is interviewed by GPS World for its Jan, 08 issue

GPS world jan 2008Jayanta Ray (JR) received his Ph.D. from the University of Calgary in 2000. He has worked in the GPS field since 1992, and is group manager at Accord Software and Systems in Bangalore, India. Alan Cameron: Tell us about Accord’s new GPS-SBAS (satellite-based augmentation systems) receiver.

JR: The development of the aerospace GPS-SBAS receiver called NexNav is complete, and it was approved by the Federal Aviation Administration (FAA) on November 1. This receiver can be used in a civilian aircraft as a primary means of navigation during en-route, terminal, approach, and landing. This is the first and so far only certified aerospace GPS-SBAS receiver of its class conforming to the latest FAA standards.

An aerospace GPS receiver is characterized by extreme reliability, high accuracy, and very good availability. Of these, reliability is the most important factor. That is achieved by creating a very reliable hardware and software.

The hardware reliability has to be very good to the extent that misleading information is less probable than 10–7 during the approach, where the aircraft is very close to the runway; that is, about 200–250 feet altitude from the runway. This is done through extensive failure mode and effect analysis, fault tree analysis of the hardware, and real-time hardware failure monitoring.

To create very reliable software, the GPS receiver software and programmable logic device (PLD) software should should be developed conforming to FAA design assurance standards DO-178B and DO-254. This requires an enormous amount of effort and a large team of avionics experts.

As we know, GPS guarantees a certain level of accuracy with say 95 percent probability. But there is no assurance of accuracy for the remaining 5 percent of the time. With SBAS, the error is bounded to a great extent. An aerospace GPS receiver takes advantage of SBAS to provide error bounds up to 99.99999 percent confidence level during approach. The receiver should also provide the highest level of integrity when there is no SBAS, through a comprehensive fault detection and fault exclusion algorithm (FD/FDE). An aerospace receiver should be able to detect and exclude any satellite failure either through SBAS integrity monitoring or through autonomous FD/FDE within time-to-alert.

These and many more requirements related to accuracy, integrity, and interference are specified in RTCA document DO-229D. The FAA gets involved in the development process life cycle right from the planning stage until completion. Throughout the process, the FAA-designated engineering representatives monitor the program and ensure conformance to FAA development standards.

In the case of Accord, we have two centers of excellence — one is the GPS and the other is the avionics software. Therefore it was synergistically appropriate for us to develop an aerospace GPS-SBAS receiver. We took more than three years from planning to the completion of the FAA-certified GPS-SBAS receiver.

AC: Does such a rigorous procedure mean the receiver is qualified for use elsewhere beside the United States?

JR: All the FAA-approved standards for the aerospace GPS receiver are exactly the same for Europe. A GPS receiver approved by the FAA is generally accepted by the European Aviation Safety Agency (EASA). Currently our NexNav receiver is primarily for the U.S. general aviation market, for more than 200,000 aircraft. We already have an airframe and two avionics OEM manufactures as our customers. But it can also be used elsewhere. NexNav receiver is flying in Europe, Australia, and in New Zealand as well.

AC: What about other products?

JR: We have built GPS receivers for the last 15 years, primarily for the land transportation segment in Latin America, Southeast Asia, and parts of Europe. In this market we partnered with Analog Devices (ADI) of the United States.

We have also developed a GPS L2C receiver prototype and were able to acquire and track the L2C signal within three days of the first IIR-M satellite beaming the L2C signal, December 16, 2005. This was published in the Innovation section of GPS World [May 2006].

We have also developed a 24-channel GPS/GLONASS receiver to support domestic market needs. On the indoor GPS front, in partnership with ADI we have created a new chipset, which will be available in mid-2008. We have benchmarked the performance of our solution with the best in the industry and are confident about its success. It is an autonomous GPS and its variant uses assisted GPS protocols using GSM, GPRS, or CDMA networks.

AC: Tell us about GAGAN project.

JR: GPS-Aided Geo-Augmented Navigation System (GAGAN) is the Indian SBAS. We are not directly working with the GAGAN program yet, though we have used NexNav to track the GAGAN satellite. We look forward to working in the initial experimental phase. We have been working with the Indian Space Research Organizatin (ISRO) since 1999. ISRO has used our GPS-based satellite positioning systems for all their LEO missions for the past eight years.

AC: How will GAGAN affect the international GNSS marketplace?

JR: WAAS in the United States and MSAS in Japan are now operational. EGNOS will be ready soon in Europe. However, there is a gap between EGNOS and MSAS which will be filled in effectively by GAGAN, so that one can have seamless travel from Europe to the Asia-Pacific region.

Another very important aspect is that the problem of large ionospheric scintillation in the Indian region will have to be solved before GAGAN can be declared operational. The ionosphere is very turbulent in equatorial and tropical regions. It’s a big challenge to model the ionosphere well enough to get required GPS performance for aircraft navigation and landing. A lot of countries are waiting to see how this problem gets solved in India. Once solved here, it can be used elsewhere; the single-shell model used in WAAS and other regions is not really applicable for India. Once GAGAN becomes operational, similar systems can come up in countries such as Brazil.

The International Civil Aviation Organization (ICAO) has a mandate that eventually aircraft navigation should primarily use satellite-based systems such as GPS, GLONASS, or Galileo along with SBAS and/or ground-based augmentation systems (GBAS). So it is all but certain that eventually the world will adopt GAGAN or WAAS-like systems. GAGAN is expected be operational around 2010 or 2011.

Accord and Spectralux™ Announce WAAS Beta-3 Sensor

October 11, 2006, Accord announced today, a strategic alliance with Spectralux Corporation based in Redmond, Washington, USA to create GNSS sensor products for civil aviation applications. The product named NexNav™, is a GNSS sensor circuit card assembly (CCA) designed to meet the WAAS Beta 3 requirements.

WAAS Beta-3 is a performance standard for Global Positioning System (GPS) receivers that allows for LPV (localizer performance with vertical guidance) approaches at many airports in the United States. LPV approaches allow for low-visibility landings without the need for expensive instrument landing system (ILS) installations for each runway. It is widely expected that many regional airports will be certified for LPV approaches in the next few years, reducing the number of aircraft diversions due to low visibility.

NexNav incorporates Accord’s proprietary high precision GPS receiver core technology. It meets the RTCA DO-229D minimum operational performance standards and has been developed by Accord compliant to DO-178B and DO-254 standards. Spectralux will provide design integration, manufacturing, certification and product support for NexNav. The FAA TSO is scheduled for the first quarter of 2007.

NexNav measures only 15 square inches and weighs 150 grams. It can easily be fitted into an existing LRU (line replaceable unit) or provided as a standalone module. NexNav features 12 GPS and 3 SBAS channels with GPS acquisition and tracking sensitivity of -136 dBm and -140 dBm, respectively. The unit consumes 5 watts of power in a typical installation, and has an update rate of 5 Hz.

“Beta-3 is the highest aerospace performance standard for GNSS available today,” said J.M. Sundaresan, managing director of Accord. “The NexNav sensor will allow all kinds of OEMs who need precise information on position, velocity, and time to get a solution that will fit their needs.”

“We identified a clear market need for a Beta-3 card that can be configured to fit our customers’ needs,” said Michael Burke, president of Spectralux. “Our launch customer specified a stacked configuration, but it can easily be produced in other form factors.”

NexNav is represented exclusively by Phoenix Aerospace Consulting Group of Phoenix, Arizona, USA, a business development consultancy with over 20 years of experience in avionics. For more information on NexNav, visit http://www.nexnav.com

Automobiles benefit from GPS in Telematics - Deccan Herald
On: July 20th, 2005

When GPS technology was introduced by the US department of defence way back in 1984, it was envisaged to be used predominantly by the military. However today it is the civilian community that has benefited immensely from the GPS technology, so much so that upwards of 80 percent of the users are from this segment. The civilian community has contributed immensely to the development of the GPS receiver technology by giving birth to several enhancements to the basic GPS functionality. One such enhancement to arise out of this civilian involvement is the advent of 'telematics' for automobiles. ...

Automobiles benefit from GPS in Telematics

What is Telematics

Telematics is the amalgamation of technologies that in the end serve one or more of the following needs in an automobile.

  • Navigation
  • Entertainment
  • Communication
  • Security
  • Tracking

Let us look at each of the above technologies in some detail.

Navigation in an automobile provides the capability to the driver to navigate from one place to another with the help of GPS.GIS (Geographical Information System or simply put, digital map data)and audio/video prompts turn by turn navigation,voice prompts for route guidance etc). For example, imagine a person who arrives at Bangalore and rents a car to travel from the airport to MG Road. IF the rental car has a Telematics unit installed, our friend could enter the starting point (Airport) and the destination (MG Road) on the map and take off. GPS would provide instant-to-instant position and the navigation algorithms can decide for the driver whether to take a left or a right turn ahead of time and play a recorded voice instructing him to do the needful.

Entertainment mainly consists of audio/video directed towards entertaining the occupants rather than navigation. This would be running an MP3 player or playing a movie on a display screen.

Communication enables the occupant to communicate with the external world over the wireless network. This could be GSM,CDMA or any other wireless communication technology. Instead of picking up a phone, dialing and then talking, a person can initiate a call just by speaking outs commands. Automatic speech recognition software can recognise the command (fro example, dial XYZ) and place the call. This, of course, requires the database of the persons and their phone numbers to be already stored in the unit. The microphone and the speaker of the phone are connected to the car audio system and hands free environment is created.

Security is an added features that is used both to save lives and also as a deterrent to vehicle theft. For example, a GPS+GSM system could relay the position of the vehicle to another caller thereby identifying the location of a stolen vehicle. The position computed by the GPS can be transmitted by the GSM phone through the use of popular SMS messaging service. The position can be plotted onto a digital map to trace the stolen vehicle. Tracking again is feature by which a remote vehicle can be tracked using any of the wireless links

The role of GPS in telematics

GPS technology plays an important role in the navigation, security and tracking needs of the vehicle.By providing the all-important positioning information, a GPS receiver embedded in a vehicle could be a guide for a newcomer into the city with the help of digital map and/or route guidance. It could alert the emergency service by relaying the position of the vehicle through any of the wireless networks. The same means could be used to track the vehicle either to detect theft or to manage a fleet.

GPS to the aid of travellers

People travel to different cities for various reasons. Often, they do so in their own vehicles or on rented ones. It is also common to find out the same people stopping by the roadside and asking for directions.

The problem of such travellers can be summarised in the following statements:

  • I do not know where I am (which street. Cross road, locality etc)
  • I know where I have to go (address of the destination is known)
  • I do not know how to get there (the shortest route, avoiding one-ways etc)

GPS is a made-to-order technology for such problems. Problem statement one is easily addressed by the GPS technology. It provides the user with a precise co-ordinate of his/her location. A digital map that can interface with the outputs of the GPS receiver can solve the problem statement 3. Digital maps usually provide prompts for the user to enter the destination. The map software looks up the co-ordinates of the destination from its exhaustive database. It compares the destination co-ordinates with the current co-ordinates given by the GPS receiver and identifies the shortest route to the destination. The position updates from the GPS receiver enable the user every second to monitor the direction he is headed by looking at the trace on the map. However, there seems to be only one hitch. With more and more streets being converted to one ways in the major cities, our user could end up paying a hefty fine if the map software is not the recent one.

GPS as a security system

Vehicle theft is a major concern all over the world. A simple mechanism to detect/prevent theft would be possible using GPS and the GSM link.

As from the previous case study, the position co-ordinate of the stolen vehicle can be precisely obtained using GPS. Using as GSM link, the instantaneous position can be obtained by a simple SMS call. A more sophisticated way would be to use the combination of GPS and GSM to effectively disable the vehicle. If the owner detects that his/her vehicle is stolen, he/she can send a command through the GSM. The GSM and GPS are interfaced to be a part of the vehicle electronics network GPS technology has emerged as a boon to the automobile industry. The onus has shifted from just being able to travel from one place to another to a different plane where people are also worried about the time and distance to travel, the quality of travel and above all the safety factor.

GPS for better flights - The New Indian Express

BANGALORE: Come winter, and fog plays havoc with air services in our national capital and other northern India airports due to poor visibility leading to diversion or cancellation of flights. This has been happening year after year and there is no sign of any improvement, as yet. Global Positioning System (GPS) can play the critical role of safe landing and take-off of the aircraft at including very poor visibility condition, avoiding disruption of air travels.

Conventionally aircraft uses an Inertial Navigation System (INS) for navigation in the air. The INS has a very good short-term accuracy, but poor long-term accuracy. The INS derived position, if un-corrected, is too erroneous after a few hours of flight and unsuitable for aircraft approach and landing. The presently available Nav-aids for approach and landing are too many, terrestrial in nature, expensive to maintain and technologically inadequate for better usage of airspace to facilitate more air traffic without compromising the safety margin of the aircraft and passengers. GPS can be used for more efficient use of airspace, preventing delays to passengers and saving fuel costs for airlines in the coming years.

GPS alone provides accuracy in the order of 10 m, that is sufficient for cruising altitude mid-air aircraft navigation. However it is vastly inadequate for aircraft approach and landing into an airport. Overlay systems such as Wide Area Augmentation System (WAAS) of United States of America (USA), European Global Navigation Overlay System (EGNOS) of Europe, Multifunctional Transport Satellite Augmentation System (MSAS) of Japan and our own GAGAN are intended to detect any failure in the GPS satellite and improves the position accuracy in the order of 2-5 m. Federal Aviation Administration (FAA) of USA has commissioned WAAS in 2003-04 and allowed aircrafts to use GPS-WAAS system as a primary mode of navigation during high altitude flight, aircraft descent and precision approach up to a decision height of 250 ft. With almost all aircraft presently using GPS receiver, FAA has last month announced a tighter air control by allowing aircraft to have a height separation of 1000 ft, down from 2000 ft, which is expected to save more than $5 billion over the next decade. FAA is now undertaking trials of another augmentation system to GPS called Local Area Augmentation System (LAAS), which is a ground-based pseudolite system giving instantaneous correction to GPS signals, integrity of the GPS signal, as well as additional ranging signal. With the help of LAAS and WAAS, GPS can then be used for up to CAT III. This will result in a lot more approaches not available earlier, less time for take-off and landing at even poor visibility and adverse weather conditions, reduction in cost - all without any reduction in safety margin.

Indian Space Research Organization (ISRO) and Airport Authority of India (AAI) has spearheaded Indian efforts towards satellite-based navigation by initiating installation of a WAAS-like overlay system for the Indian aerospace called GPS And Geostationary Augmentation Navigation System (GAGAN). India being a country in the tropical region, has a very different ionospheric anomaly and scintillation compared to that of the USA. Indian scientists are trying to model the ionosphere over the Indian region by studying the ionospeheric behaviour at about two dozen locations across India using advanced L1/L2 GPS receivers. However, Indian airports are still way behind in terms of having infrastructure for GPS-based precision approach. Director General of Civil Aviation (DGCA), Airport Authority of India and other concerned authorities should closely monitor the satellite-based aircraft navigation and precision landing related developments in the United States. They should encourage the local GPS industry, which already has developed indigenous GPS-WAAS receiver technology for civilian aircraft and exploit them for use in Indian airports and aerospace.

All future aircraft shall have GPS-based avionics for navigation and landing. Further, all older aircraft are being retrofitted with GPS-based avionics for the same purpose. The International Civil Aviation Organization has a CNS/ATM program to move away from terrestrial based techniques and moving closer to satellite based techniques for aircraft navigation and the gradual transition is expected to happen in the 2010-2012 time frame. India, being a leader in satellite and satellite launching vehicle technologies, should also gear up to take leadership in the satellite based navigation and landing to make a safe journey by air.
