摘要: “北斗一号”系统采用有源定位方式,导致系统存在不足,如用户数目存在上限等。若系统采用无源定位方式,则又存在观测量不足的问题。文章介绍了一种无源组合导航技术 无源双星/多卜勒组合导航技术,对无源双星/多卜勒组合导航定位原理进行方案分析和设计,并对其进行了仿真试验,仿真结果显示该技术可减小多卜勒导航定位误差、提高导航精度,并实现北斗无源定位。最后分析了此方案的可行性并对其应用前景进行了展望。

Abstract: The “BD-1” system usually adopts active positioning method, which possesses some shortages in the system application, such as limited number of user. The restriction of implementing passive positioning is the lack of enough satellites. A passive combination navigation technology called passive double satellites/Doppler combined navigation technology is presented in this paper. The principle of the passive double satellites/Doppler combined navigation orientation is analyzed and designed. A simulation test is conducted to evaluate this combined navigation technology. The result shows that this technology is able to reduce Doppler navigation positioning error, improve navigation accuracy, and implement passive positioning based on “BD-1” system. Finally, the feasibility of this method is analyzed as well as its application prospect.

Key words: Beidou, passive positioning, combined navigation, Doppler navigation
