摘要
以北斗卫星I支路频点为例,从消除或减弱电离层影响、对流层影响和观测噪声与多路径误差3个方面分析COMPASS三频数据线性组合的优化选取问题,并通过MATLAB模拟,给出一些典型的组合,分析它们可能的应用,为COMPASS三频数据线性组合的优化选取提供一些借鉴。
Taking the COMPASS system I frequency as the example, from three aspeets of eliminating or mitigating the ionospheric delay, tropospheric delay and observation noise, it analyzes systematically the optimal selection of COMPASS triple-frequency coefficient of linear combination. At last, by MATLAB simulation, some typical combinations are given and analyzed on the possible applications, which can provide some reference to the optimal selection of COMPASS triDle-freauencv linear combination.
