Description
Summary:In order to estimating satellite interfrequency bias T gd for the anomalously behaving SVN49, a modified JPL GIM software suite is presented. This research assumed that the single-frequency user will not need to perform any modification in the receiver software and will not need any detailed knowledge of the satellite anomaly using the code observable. We performed a point positioning analysis and investigated the range residuals for SVN49. It was discovered that the new satellite bias estimate resulted in near zero mean residuals with the shape of P2-P1 and L1-L2 observables being consistent with shapes from other satellites. Also, computed is a 10-day average of the estimated satellite interfrequency bias T gd , which turned out to be −19.13 ns.
