  1. Present and Future of China Satellite-Based Augmentation System China Satellite Navigation Office February 2014

  2. Contents • Present of China Satellite-Based Augmentation System • Future of China Satellite-Based Augmentation System

  3. Present of China Satellite-Based Augmentation System BeiDou Satellite Navigation System is designed integrating of the basic navigation system and the Satellite-Based Augmentation System, and it can provide basic navigation service as well as differentialaugmentation service. The service has been on line since Dec. 27th, 2012. At the same time, experiments on the Satellite-Based Augmentation technology that provides service to GPS L1 C/A based on BeiDou GEO satellites have been implemented, and the results have demonstrated its feasibility.

  4. Present of China Satellite-Based Augmentation System • System composition • 3GEOSatellites（80°E, 110°E, 140°E） • 29monitor stations • 1 master control station

  5. Present of China Satellite-Based Augmentation System • B1 I of Signal in Space, Main content is as follows, detail is on ICD • System accuracy: 3-5m; Other performance are beening tested

  6. Contents • Present of China Satellite-Based Augmentation System • Future of China Satellite-Based Augmentation System

  7. Future of China Satellite-Based Augmentation System • Aims • Service area :China and surrounding areas • Support single frequency and multi-frequency users • Multi-system augmentation ability • Consider the possible of being compatible and interoperable with EGNOS and WAAS • Provide CAT-I service

  8. Future of China Satellite-Based Augmentation System • Technology roadmap • Launch 3GEOsatellites：80°E,110°E,140°E • Increase ground monitor stations: About 40 stations(China and surrounding areas) • Upgrade the algorithm of master control station : Provide dual frequency, multi-system service • Increase B1C(L1),B2a(L5) signal, being compatible and interoperable with SBAS • Broadcast augmentation information：Broadcast ephemeris/clock corrections, grid ionospheric correction and its corresponding integrity parameters. The format meets international standards.
