现阶段北斗卫星导航系统可用性分析
Usability Analysis of Beidou Satellite Navigation System at the Present Stage
摘要
Abstract
Beidou Satellite Navigation System, which is run by our country herself, has already launched 9 satellites. With 3 GEOs and 3 IGSOs,a '3+3' constellation has been formed in the Asia Pacific region. The research on the system ability has a profound impact on the further construction and improvement of the Beidou Satellite Navigation System. In this paper, a simulate analysis of DOP and the visible satellites of the constellation have been made through STK and mathematica. As is shown from the simulate analysis, in the '3GEO+3IGSO' constellation serice area, the visibility is good and the positioning is quite accurate, which make it clear that the '3GEO+3IGSO' constellation has a high level of usability.关键词
