摘要

为了评估武器装备在极区的卫星导航定位性能,从可见卫星数、PDOP值以及定位精度等方面对比分析了GPS、北斗以及GPS/北斗组合系统的定位效果。对南极中山站数据分析的结果表明:北斗可见星数在13~21颗之间,一天内可用性达到100%,PDOP值在1~2之间变化,伪距单点定位在东北和天方向的精度分别优于3m和6m,定位精度明显优于GPS;北斗/GPS组合系统三维精度相对于GPS和北斗单系统分别可提高48%和15%。

Abstract

In order to assess the satellite navigation and positioning performance of the weapon equipment in the polar region, the visible satellite number, PDOP value as well as SPP( single point positioning) accuracy are analyzed through compare GPS, BeiDou, and the GPS/ BeiDou integrated system. The results of data analysis on the Antarctic Zhongshan Station indicate that BeiDou satellite number in view vary between 13-21, the availability can reach up to 100% for one day, PDOP values vary between 1 and 2, the precision of BeiDou single point positioning are 3 m and 6 m in east-north and up component, respectively; the precision of BeiDou-only is much better than that of GPS solutions, the precision of integrated system compared with the GPS and BeiDou system can be increased by 48% and 15% in three dimensional.

Key words： BeiDou navigation satellite system; PDOP; single point positioning; antarctic region
