EGNOS对流层延迟改正模型及其精度分析

对流层延迟是GPS定位中一个主要的误差源,目前处理对流层延迟的主要方法是通过模型法、差分法等;当基线的距离较短时,基线两端气象条件基本相同差分法可以很好地修正对流层延迟误差,当基线的距离很长时,由于基线两端的气象参数差别较大差分法不能很好地消除对流层误差,模型法却能很好地消除对流层误差.对EGNOS模型进行了详细的介绍...

Delay Model and Accuracy Analysis of EGNOS Tropospheric

Tropospheric delay in GPS positioning is a major source of error,in the handling of the main methods of tropospheric delay correction through model,difference method,etc,weakening or elimination of tropospheric delay error.When the distance is short baseline,baseline ends meteorological conditions are basically the same,difference method can be very good correction troposphere delay error,when the baseline,due to the long distance between the meteorological data at baseline large,difference method can't eli...
