摘要
CORS网能快速实时定位、导航且可以避免临时基准选站不当而引起的起算偏差,这使得作业的精度有了保证。由于利用现有的卫星钟差模型进行精密单点定位稍有些不足之处,该文讨论了基于CORS网提供的卫星钟差信息内插的方法得到更高精度的卫星钟差数据,以提高精密单点定位的精度。
CORS can provide real-time position rapidly, navigation and avoid starting crate aevlauon caused by the improper of temporary benchmark choose, which ensured the precision of surveying. Be-cause the existing satellite clock errors model for precise point positioning has some deficiencies, the sat-ellite clock errors are gained by fitting its grids in CORS to get higher precision of the satellite clock errors data , so as to improve the precision of precise point positioning.
