【摘要】 研究了提高伪距观测值精度的三种方法,即:相位平滑伪距、Hatch滤波和卡尔曼滤波,探讨了它们的异同。在此基础上,利用自己编写的程序,分别用三种方法平滑后的伪距观测值进行单点定位计算,经与IGS跟踪站的已知坐标的对比,得出了有益的结论。更多还原

【Abstract】 Three methods of improving the precision of pseudo-range observations are studied,they are carrier-smoothed code,Hatch filter and Kalman filter,and their similarities and differences are discussed firstly.Based on this,by self-compiled program,the point positioning is calculated for the pseudo-range observations of carrier-smoothed code with three methods.Compared with the known coordinates by IGS station,some beneficial conclusions are obtained.更多还原
