Determination of Navigation Satellite Clock Bias Using SLR and GPS Dual Frequency Phase-Smoothed Pseudo-Range Data

  • The bias of GPS35 satellite clock is computed by using the data observed on October 2005.The results compared with the GPS 35 clock bias of IGS.By comparison and analysis,the following facts can be drawn:① It improves the precision of pseudo-range using phase smoothing pseudo-range,and improves the precision of satellite clock bias when the clock bias is calculated by using SLR and smoothed pseudo-ranges data.② The precision of navigation satellite clock bias is better than 0.3 nanosecond(1σ),when the bias is calculated by using SLR data and smoothed pseudo-ranges data.There is no systematic error between our results and IGS's clock bias.
