Aims



Technology roadmap

  • Technology roadmap

    • Launch 3 GEO satellites: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.
