| Abstract: | 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. |
