| Abstract: | The developing trend of global civil satellite navigation system is presented. The situation of Chinese satellite navigation system and necessity for constructing the second generation of satellite navigation system is described, and the characteristic of a regional navigation system is investigated. The application of the circle orbit synchronous satellite is analyzed in regional navigation system, and a constellation composed of geostationary and inclined circle orbit synchronous satellites is designed. Its performance is preliminarily analyzed by computer simulation. Result shows that a constellation of 7 satellites can meet the basic requirements for covering all over China territory and its neighbor area, and obtain the satisfactory precision in the area. |
