GAGAN Expands Satellite-Based Civil Navigation


Background

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

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

    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.


    Sbas benefits1

    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.

    • 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
