摘要
对伪卫星实际应用中所面临的几项关键技术进行了论述,并重点研究了伪卫星空中基站的自身定位问题。从陆地上空伪卫星和海上伪卫星两个方面进行了仿真计算,分析了其几何精度因子随定位星座布局变化的规律,设计了最终的定位方案。
This paper discusses several key technique problems of pseudo satellite existed in practice. It primarily analyzes self-positioning problem of the aerial base station of pseudo satellite. The simulating calculations are carded out in two cases: when the pseudo satellite is above the ground and when the pseudo satellite is above the sea. It describes the changing rule of geometric dilution of precision with respect to the constellation distribution and devises the final positioning scheme.
