摘要
详细论述了电离层、对流层对卫星导航信号传播时延的影响,讨论了修正大气层时延影响的相对定位、延迟模型改正方法,详细分析了双频观测量电离层时延误差修正方法。
The effect of the ionosphere and troposphere on satellite navigation signal delay is presented. The relative positioning and delay model correction algorithm for correcting the atmosphere effect are discussed. The method of dual - frequency observation correcting ionosphere delay error is analyzed in detail.
