摘要
首先介绍了北斗载波差分模型,根据该模型分别对影响定位性能的北斗可视卫星数、DOP值、CA码噪声、载波噪声等进行了分析,最后进行了北斗载波差分精度测试,并与GPS进行了对比。结果表明,北斗载波差分定位精度与GPS定位精度基本相当,定位速度较快。
The Beidou Carrier phase Differential Model.Based on this model is introduced,we Analysise the facts which would influence the positioning precision such as the numer of the satellites,DOP value,CA code noise,carrier noise ect.At later,we test the precision of the Beidou Carrier Differencetial and Compare to the GPS.It shows that the Beidou Carrier Differencetial has the same precision of the GPS,even more rapid.It will be satisfy to construct and repair r the airport rapidly.
