摘要
为了研究BDS运用于CORS定位服务时的定位精度及GPS可能引发的安全性问题,测试了BDS精密单点定位精度,利用Ambizap算法解算了甘肃省CORS网站观测数据,比较分析了BDS CORS与GPS CORS的精密单点定位结果。结果表明,坐标分量差值在mm至cm级。
In order to study on the positioning accuracy of BDS when used in CORS positioning service and on the security issues caused by GPS,the paper tested the positioning accuracy of BDS PPP,calculated the observed data in Gansu province CORS with Ambizap algorithm,and comparatively analyzed the precise point positioning results of GPS CORS and BDS CORS.Result showed that the deviation of coordinate components would be between mm^cm level.
