摘要
讨论近地卫星利用GPS 全球定位系统进行自主定轨的精度问题,建立了定轨精度与等效三维定位精度之间的关系,然后利用这种关系来推算C/A 码用户所能获得的定轨及位置精度。分析结果表明,10m 量级的定轨精度是可以达到的。
This paper discusses the accuracy of autonomous orbit deter-
mination for near-earth satellites by using GPS and related issues.At first,
a relation between the orbit accuracy and the equivalent 3-dimension posi-
tion accuracy is established,the potential orbit accuracy which can be
obtained by C/A-code users is calculated then by using this relation.Results
show that a ten-meter level orbit accuracy can be achieved for onboard
C/A-code users.
