For several months, two Navstar satellites have been intensively tracked by three monitor stations located in California, Hawaii and Alaska. Analysis of this tracking data shows that its short-term quality is high. This report discusses the tracking data, a technique for analyzing the data, and the results of this analysis. The application of this technique to evaluate the performance of atomic frequency standards in the satellite is presented. The effect of two-frequency ionospheric correction on the short-term quality of the tracking data is also discussed. (Author)
