计算了由于大气色散效应造成的信标光与发射主激光的实际天顶角之间的角间距 ,其中考虑了天气条件、地理位置、发射天顶角和信标波长等影响因素。

The total delay can be calculated from the zenith delay.

为了对大气传播延迟误差进行修正,达到精确测量的目的,推导了天顶延迟的理论计算公式;在大仰角情况下提出了一种简化的映射函数,并把它与连分式映射函数进行了比较。

After some major zenith delay corrective models are analyzed and several mapping function models in continued fraction are discussed and induced,it is concluded that the former corrective models are only based on the atmospheric models of spherical symmetric distribution and adopted almost same isotropic corrective models.

在分析了一些主要的天顶延迟改正模型,并对几种连分式形式的映射函数模型作了归纳后,认为:前者只能都基于大气球对称分布模型,采用差不多相同的各向同性的改正模型,各种映射函数模型的连分式之间,差别仅是形式上的,没有实质性差异。

A new method utilizing zenith observing to calibrate star sensor was proposed.

提出了一种利用天顶观测来进行星敏感器标定的新方法。
