11 10 BeiDou Orbit Determination
12 11 BeiDou GEO Orbit Determination Precise orbit determination challenging for GEO satellites Weak and almost invariable tracking geometry w.r.t. ground stations: Altitude of ~36,000 km (~20,000km for MEO) Satellite position almost fixed with respect to the Earth Lack of apparent satellite motion induces strong correlations between estimated parameters such as: Satellite position, velocity, clock Receiver clock, troposphere Multipath (code & phase)
13 12 BeiDou GEO Orbit Determination Stabilize the solution with GPS as aiding system Enhance tracking geometry, e.g. by: Use of code observations Low elevation cutoff Tailored solar radiation pressure model for GEOs: Proper parameterization to reduce correlation Orbit normal attitude mode considered Geostationary satellites perform frequent station-keeping manoeuvres: Approximately every 4 to 10 weeks Shown in next slides based on broadcast ephemerides Orbit processor states need to reconverge after manoeuver

24 23 Horizontal Position Error after Convergence
25 24 Vertical Position Error after Convergence
26 Summary All BeiDou satellites now included in RTX transmissions and rover processing: BeiDou GEO satellites provide the greatest challenge for precise orbit determination Internal consistency checks indicate that mean component RMS errors in BeiDou orbits are: 2cm for GEO, and 1cm for ISGO / MEO satellites BeiDou orbits from RTX system, agree with external sources to cm/dmlevel for MEO / ISGO satellites and meter-level for GEO satellites. Adding BeiDou satellites to Trimble RTX TM positioning: Reduced convergence times by 25-30% over the Asia Pacific test region Improved (95%) Horizontal and Vertical position errors improved by 18% and 7% respectively 25
