瞬时极坐标与时号改正的自动解算

天文测量数据处理软件在解算经纬度、方位角和人仪差时,需要预先计算出瞬时极坐标值和测前测后时号改正值。本文使用天文数据处理软件的准备文件数据直接进行极坐标和时号改正的解算,对传统内业解算步骤进行编程,减少内业计算的人工干预和数据处理环节。实验与分析表明,自动解算方法能够显著提高作业效率,减少计算的人为误差。

Autosolving for Instantaneous Polar Coordinates and Time Signal Correction

When using astronomic surveying data processing software for the solution of longitude,latitude,azimuth and personal and instrumental equations,instantaneous polar coordinates and time signal correction are required to be worked out in advance.In this article it is proposed that instantaneous polar coordinates and time signal correction can be calculated directly based on preparative file data for astronomic software,and decrease manpower interventions and data processing steps in work flow by programming o...
