GAGAN Enabled Receivers

GAGAN signals are compatible with other Satellite Based Augmentation Systems like Wide Area Augmentation System (WAAS) of USA, Multi-satellite Augmentation System (MSAS) of Japan & European Geostationary Navigation Overlay Service (EGNOS) of Europe making all the systems interoperable.

To ensure global compatibility in civil aviation, the use of radio navigation aids is governed by the ICAO (International Civil Aviation Organization) Standards and Recommended Practices (SARPs). One of the most important requirements was to ensure that any properly equipped aircraft could benefit from these regional systems by installing a single receiver. RTCA Inc has developed the Minimum Operational Performance Standards (MOPS) for SBAS equipment. The main reference document is DO229 version C/D. This document describes the standards for all GAGAN/EGNOS/WAAS/MSAS receivers. Receivers complying with these requirements, as determined by the appropriate Technical Standard Order (TSO) provide full GAGAN/EGNOS/WAAS/MSAS compatibility.

GAGAN can be used for non-aviation applications also such as Agriculture, Survey/Mapping, Railways, Marine applications, Timing applications, scientific research, Location Based Services etc.

Now GAGAN SIS is also available from PRN 132.
