| 摘 要： | 本文提出了一种可自动估测电波传播误差的五星单频定位和选星算法。仿真结果表明,在仅有电离层误差条件下,五星单频定位的误差明显小于未加电离层修正的普通四星定位,接近千差分定位精度。

| Abstract: | In this paper, a new single--frequency positioning method using five satellitesand algorithm of selecting these satellites are proposed, with which the propagationzenith time delay error can be estimated authomatically. Simulation results show that,when the source error is only due to ionospheric delay, the positioning error withthis method is less than that of the conventional positioning using four satellites, andis hardly different from the error of the differential positioning. |
