Chart 7

GAGAN transmit signal similar to GPS signal

GAGAN satellites can be used as additional GPS satellites

This increases the number of visible satellites in urban canyon, forest canopy and when an aircraft maneuvers

This improves the DOP and availability of GPS

Accord’s NexNav line of GPS-WAAS/GAGAN receivers are approved by the Federal Aviation Administration (FAA) of USA for use in commercial civil aviation

Receiver conforms to DO-229D, DO-301, DO-160F, DO-178B, DO-254, TSO-C145c etc.

Technology and product indigenously developed by Accord. Measurement accuracy: 10 cm

Accord’s GPS-SBAS/GAGAN Receiver flying in hundreds of foreign aircraft in USA, Europe and Australia

Receiver was also used for validation of GAGAN Signal in space

Accord’s FAA Certified GPS-GAGAN Receiver




Chart 10

Besides navigation, GPS-GAGAN/SBAS receiver is at the heart of ADS-B, for surveillance

USA has mandated ADS-B Tx for all new and old aircraft flying in US National Airspace by 2020

Accord’s GPS-SBAS receiver meets all the FAA requirements for ADS-B including AC 21-165 and the first in the world to do so

Accord’s FAA Certified Rx for Surveillance

Conclusions




Chart 13

GAGAN improves the reliability, accuracy and availability compared to GPS-only solution

High dynamics users could use GPS safely and confidently ONLY IF GAGAN declares it healthy and un-corrupted

Accord developed completely indigenous GPS-SBAS/GAGAN receivers for Indian defence

Accord’s GPS, GPS-GLONASS etc. GNSS receivers are used by Indian defence in all key applications for the past one decade

Completely customized in terms of interfaces, size, shape, functions, dynamics and other features

Conclusions




Chart 22

Differential GPS (DGPS) is the most widely used technique for accurate positioning for coast guards and fishermen

DGPS position errors grow proportional to the distance between the DGPS reference station and the user receiver

GAGAN is the NATIONWIDE DGPS system, which does not require any DGPS reference station or Modem

GAGAN provides better accuracy uniformly compared to DGPS and most suitable for Coast Guards and Railways

GAGAN Rx for Coast Guards, Railways

GPS Module for AIS




Chart 23

Conclusion

GAGAN brings a host of benefits to the user in the areas of integrity, accuracy and availability

GAGAN provides a more cost effective and better performing alternative to DGPS

Accord’s has indigenously developed and GAGAN enabled Rx for Indian market for

Civil aviation

Defence, coast guards, railways

Consumers and land applications
