 分析了对流层延迟的基本特性及常用的处理措施,通过实例表明了不同对流层的处理方法对大地高精度有较大影响:当基线两端高差较大时,即使基线较短,其气象条件也有所差异,仅仅通过差分或模型改正仍不能消除对流层延迟的影响,残余的对流层延迟仍然影响大地高的解算精度,通过对残余对流层延迟进行估计能够明显改善大地高的精度。 更多还原

【Abstract】 The basic characteristics of tropospheric delay and its commonly used treatment measures were analyzed in this paper.It had shown that the different pairs stratospheric high-precision approach had a greater impact on the geodetic height by examples.When the large height difference across the baseline,even the short baseline,the weather conditions was different,the effects for tropospheric delays could not eliminate only by difference or Model correction in this condition,and the residual troposp... 更多还原
