摘要
Systems and methods for enhanced broadcast ephemeris are described. These systems and methods include the calculation and transmission of globally and locally optimized parameters of the broadcast ephemeris of a global navigation satellite system, such as ionosphere, clock, and orbital parameters of a GPS satellite and receiver. The locally-optimized satellite clock parameter compensates for geographically-specific signal errors that cannot be compensated by any global parameter of the broadcast ephemeris. The enhanced broadcast ephemeris error corrections are transmitted in the conventional RINEX format.
