Frequency stability estimation of Compass On-board clock based on smoothed broadcast ephemeris

2013 Joint European Frequency and Time Forum & International Frequency Control Symposium (EFTF/IFC), 2013
For Compass and Galileo systems which are currently in their stage of construction, it is difficult to obtain precise on-board clock short-term stability for common users. In this paper, a simple estimation method based on smoothed broadcast ephemerides is proposed, which only needs observation from one single receiver.

Precision Analysis of CNAV Broadcast Ephemeris and Its Impact on the User Positioning

2017
GPS broadcast ephemeris error is an important factor affecting the real-time positioning accuracy. Since April 2014, the IGS provided two new broadcast ephemeris products, namely LNAV (Legacy Navigation Message) and CNAV (Civil Navigation Message). Compared with LNAV, CNAV was broadcasted only on Block IIR-M and IIF satellites.
