摘　　要：本文对各种GPS相对差分技术进行了研究 ,提出了利用Kalman滤波确定高动态情况下载波相位整周数的方法。对用GPS相对位置差分、GPS相对伪距差分。Three methods of relative differential GPS are studied in this paper, and the method determining the integer ambiguities of GPS differential carrier phases under the high dynamic environment by kalman filter is presented. Primary simulations determining the fly-by orbit by the relative differential position of GPS , relative differential pseudo range of GPS and relative differential carrier phase of GPS are made.
