摘要
本文通过卫星激光测距全球网和区域网（北美网和欧洲网）定轨结果的比较，分析了区域网定轨所能达到的精度。结论是区域网所测定的轨道可替代全球网轨道，满足区域性大地测量和地壳运动研究的需要。
Comparing and analysising the results of orbit determiration derived from SLR global and regional network, we drew conclusion that in area geodesy, the orbit determined by global network can be substituted with the orbit by regional net-work.
