GAGAN – Adoption within Asia Pacific Region Plan/Opportunities India
APV 1 250 ft DH 50m VAL, 40m HAL GAGAN Expands Satellite-Based Civil Navigation
Background GAGAN achieved RNP 0.1 certification in December 2013 • Type 2 message will be available in February 2014 • GAGAN signals available in Indian airspace for en route navigation and non-precision approaches GAGAN system can be expanded in the region with additional sites • Software is designed to accommodate up to 45 reference stations (15 currently) • Place single string reference station at selected location • Collect and analyze data from site and concatenate to GAGAN data • Determine system performance improvement prior to site installation/integration
Projected Performance –with additional site in Mandalay Burma Without Mandalay With Mandalay
Expansion Study for GAGAN East Asia 2006 December 5 2010 March 22 2010 April 26 APV-I LPV 200 Availability Ionospheric activity in the equatorial region < 50% >= 95% = 100% >= 99%
GAGAN Expansion Benefits • SBAS expansion and growth • Preliminary analysis to add sites in neighboring countries show improved performance • Economies are eager to collaborate • GAGAN service can be leased to neighboring countries • SBAS enables meeting ICAO Performance Based Navigation requirement (by 2016) • Aircraft RNP and RNAV systems performance requirements be defined in term of accuracy, integrity, availability, continuity and functionality of a particular airspace. • Low cost solution to attain SBAS capabilities; available GEOs, processing & uplink stations • APEC GNSS 2011 Meeting Initiatives – • SBAS regional expansion • FAA charter to expand SBAS globally • Raytheon continues to support the FAA on the charter • Equatorial Region Solar Max Study • ICAO issued Standards for solar max data collection • ICAO initiative to standardize data collection – data can be shared among countries • GAGAN is the only SBAS system that has enhanced algorithm specific for equatorial region
SBAS Benefits • Efficiency • Enables optimum routes independent of ground navaids. • Low incremental cost to expand regional system into new areas. • No new equipment required at airports to benefit from SBAS. • Reduces navigation system operating costs. • All systems are ICAO compliant, thus one aviation receiver works with GAGAN, EGNOS, MSAS and WAAS. • Economic Growth • Makes all weather air services available to more communities. • SBAS signal is also compatible with non-aviation receivers. • Several million SBAS capable receivers currently in use. • Enables many new multimodal precise navigation applications.
Safety SBAS provides other countries with a sovereign means to monitor GPS. Improved situational awareness via low cost SBAS capable avionics. Nominal vertical accuracy is less than 2m(95%). SBAS 3D precision guidance can reduce landing accidents 7-fold.* Higher Accuracy, integrity, continuity and availability for both navigation and ADS-B surveillance. SBAS provides seven 9’s of integrity (probability of a hazard 1 in 10 million per approach). SBAS Benefits • Capacity • Improves availability of RNP RNAV routes, enabling safe reduction in aircraft spacing. • Offloads major airports by providing all weather operations at secondary airports. • Covers all routes and airports within a region – not limited by VHF broadcast station range. *Flight Safety Foundation, Flight Safety Digest, May-Jun 2003
GAGAN INRES data for • Estimating Indian plate movements velocity • GCPL Network ( Ground Control Point Network ) • Station Coordinate estimation, Update GCPL network • Demonstrated rapid GCP collection using GAGAN SBAS signal with an accuracy of better than 1m with signal with an accuracy of better than 1m with observation time of 10min • Densification of GCPs through GCPL Ph3 project for gpj future high resolution Cartographic mission • Integrating GAGAN SBAS data with GIS for navigational litiapplications • Atmospheric studies –Tropousing INRES data GeoscienceGroupwillusethedataforearthquake • GeoscienceGroup will use the data for earthquake precursor study 27/01/2014
