Abstract :
Based on several two-way satellite time and frequency transfer (TWSTFT) links and multichannel time transfer modems, a positioning method to geostationary communication satellite is presented, moreover, the accuracy of the positioning is concisely estimated. The characteristics of the method are simple and practical. Especially, the positioning system is completely established on TWSTFT links, so it does not need an extra investment
