摘要
依据“北斗”双星定位原理,分析了影响“北斗”双星定位精度的主要因素,在现有双星定位方法的基础上,推导了一种“北斗”双星定位新算法,仿真计算结果表明:该算法对初值要求低,计算结果准确、可靠。
The main factors which influence the positioning precision are analyzed based on the Beidou double satellite location theory, and an improved algorithm for Beidou double satellite positioning is presented on the basis of available positioning methods. The result of simulation is shows： this algo- rithm needs less about initial value, the result is more accurate and credible.
