Accuracy Analysis of BDS-3 Experiment Satellite Broadcast Ephemeris
2018Currently, five BDS-3 experiment satellites are transmitting both BDS-2 signals and new signals for users. They are equipped with high-precision rubidium or/and passive hydrogen maser clocks. In view of the inconsistency of BDS-3 experiment satellites signals received by iGMAS and MGEX network, the experiment to determine BDS-3 orbits is carried out by

Fitting Method and Accuracy Analysis of Broadcast Ephemeris in Hybrid Constellation
2014Broadcast ephemeris parameter is an important reflection of navigation system service performance. In hybrid constellation, GEO, IGSO and MEO satellites have different dynamic characteristics which lead to different fitting performances. In this article, the basic physical meaning of ephemeris parameters are analyzed, and the evaluation for the ...

Satellite autonomous navigation algorithm analysis based on broadcast ephemeris parameters
SCIENTIA SINICA Physica, Mechanica & Astronomica, 2015At present, the satellite on-board processing and transmission capacity of autonomous navigation is not enough to support the traditional centralized dynamic navigation algorithm. In order to augment the possibility of centralized onboard processing, this paper puts forward a centralized kinematics orbit determination method which is based on the long ...

GPS ephemeris message broadcast simulation
2012The warfighter constantly needs increased accuracy from GPS and a means to increasing this accuracy to the decimeter level is a broadcast ephemeris message containing GPS satellite orbit and clock corrections. The ephemeris message is produced at the GPS MCS (Master Control Station) which receives GPS signal data from NGA and Air Force worldwide and ...
