Performance Evaluation of the CNAV Broadcast Ephemeris
Journal of Navigation, 2019The new Global Positioning System (GPS) Civil Navigation Message (CNAV) has been transmitted by Block IIR-M and Block IIF satellites since April 2014, both on the L2C and L5 signals. Compared to the Legacy Navigation Message (LNAV), the CNAV message provides six additional parameters (two orbit parameters and four Inter-Signal Correction (ISC ...

Computing satellite velocity using the broadcast ephemeris
GPS Solutions, 2004GPS has been used for applications where satellite velocities are needed as well as satellite positions. Traditionally, the position was determined from noisy code pseudoranges while the velocity came from delta carrier phase measurements. This motivates the need to have a velocity model to accompany the velocity data.

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

An 18-element GEO broadcast ephemeris based on non-singular elements
GPS Solutions, 2014Compass/Beidou2 uses uniform GPS-type broadcast ephemerides for its mixed constellation, which consists of geostationary earth orbit (GEO), inclined geosynchronous orbit and medium earth orbit satellites. The ephemeris parameters adopted by Compass are singular for the small inclinations of GEOs, and some intermediate orbital planes are currently used ...

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 ...
