| 摘 要： | 电离层延迟是卫星导航定位的重要误差源之一，为了有效消除该误差的影响，需要选择适当的电离层延迟改正方法。对电离层延迟修正精度和实时性要求不同，选用的改正方法也不尽相同。本文在分析各修正方法原理的基础上，论述了各方法的优缺点、存在问题、以及适用范围，该研究对于选用电离层修正方法具有指导意义。

| Abstract: | The ionospheric time-delay is an important error source for GNSS users.In order to eliminate this error,a good method for correcting ionospheric delay error must be chosen.However,different methods must be chosen to meet the need of different correction precise and different ability of real-time.In this paper,the author analyzed the virtue and flaw of these methods,problems existed,and the applicable area also was pointed out based on analyzing the principle of these methods.Conclusions drawn in this paper ... |
