EGNOS SDK v2 - R&D AlgorithmsSBAS RANGING** Please note that this feature can cause an error in the position accuracy since EGNOS contrary to WAAS doesnot offer currently a ranging capability.June 2012 - EGNOS Software Development Kitpag. 32
EGNOS-SDK EnhancementsR&D Algorithms: SBAS RangingPurpose: enable SBAS geostationary satellites to be used for ranging in the same wayGPS satellites are used to obtain a position, which offers an increased availability of thesystem due to an increased number of satellites, together with a possible increase in thequality of the satellite geometry which can reflect in a better position accuracy.MT9, the GEO Navigation Message, provides precise orbit information for the GEOsatellites and it is intended to be used in the position computation, similar as the GPSephemeris data is used.MT17 – the GEO Satellite Almanac Message which contains the rough location of thesatellite is used with the purpose of speeding up the acquisition having known the roughposition of the satellites.MT17 will also be used to determine in the Automatic Mode of the Ranging Functionality,if the data provided in MT9 can be used for ranging or it is provided only for testingpurposes.As opposed to GPS satellites ephemeris, instead of Keplerian elements, the ephemerisdata of the SBAS satellites consist of the Earth-Centered-Earth-Fixed (ECEF) positioncoordinates, satellite velocity and satellite acceleration.The simplification of the model for SBAS satellite positions is due to the fact that theSBAS satellites are geostationary satellites, so the change in position with respect totheir nominal position should be very small.June 2012 - EGNOS Software Development Kitpag. 33
