| Abstract: | The theory and methods of GPS precision satellite clock offset interpolation using three methods were discussed in this article,and precision clock offset interpolation were done with the practice factual data,that is the 5-minute sampling rate clock offset files.High-precision and high-resolution satellite clock offset has been gotten using the methods. |
