摘要
应用卡尔曼滤波方法于带有ＳＡ影响的全球定位系统（ＧＰＳ），ＧＰＳ的定位精度可以得到显著改善。定点现场试验和动态系统的计算机仿真表明，经度和纬度的精度可以实时地达到８米（ＲＭＳ）水平，２ＤＲＭＳ值优于２５米。
With the application of Kalman Filtering to GPS with SA,the GPS positioning accuracy can be significantly improved.The static ground test and computer simulation for dynamics situation indicate that the accuracy of LAT. and LONG.could achieve & meters realtime.The 2DRMS is about 25 meters instead of 100 meters as provided by DOD,USA.
