摘要

摘要:
低地球轨道（LEO）卫星机会信号定位技术是全球导航卫星系统（GNSS）的有效补充和备份定位手段。LEO卫星机会信号定位误差主要因素是具有时空相关性的卫星星历和星钟误差，差分定位方法虽然可以有效降低该误差，但LEO卫星轨道较低使长基线定位误差仍然较大。针对这一问题，提出基于视向矢量修正的多普勒差分定位算法。通过仿真试验验证了在长基线情况下所提算法的定位精度明显优于基本算法，同时利用实际铱星信号多普勒差分定位试验验证了所提算法的有效性。

Abstract:
Positioning technology based on signals of opportunity (SOP) from low Earth orbit (LEO) satellites is an effective complement and backup positioning solution of global navigation satellite system (GNSS). The major sources of errors to be considered in the positioning technology based on SOPs from LEO satellites are ephemeris and satellite clock errors with space-time relevance. Although the differential positioning technology can effectively reduce the above-mentioned errors, positioning error is still large in the long baseline positioning scenario due to the low orbit of the satellites. To address the afore-mentioned challenge, a differential positioning algorithm with Doppler measurements based on lines of sight correction is proposed. Simulation results show that the proposed algorithm has significantly better positioning accuracy than the basic algorithm in long baseline positioning experiments, and the effectiveness of the proposed algorithm is verified by differential positioning experiments with Doppler measurements using actual signals from Iridium satellites.
