GAGAN – Adoption within Asia Pacific Region Plan/Opportunities

GAGAN Expands Satellite-Based Civil Navigation

APV 1

250 ft DH

50m VAL, 40m HAL

BackgroundGAGAN 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

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).

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.
