摘要
本文介绍了电影经纬仪拍星精度鉴定的原理及方法,提出了采用基于GPS授时,通过修正形成天文时的方法,以及开发拍星软件,研制出野外联试标校检测仪,实现了外场对电影经纬仪的精度鉴定的自动化。并着重探讨了影响精度鉴定的有关问题。该精度鉴定方法同样适用于其它光电经纬仪的外场标校。
This paper introduces the precision measurement theory of film theodolite in outside by measuring star. The way based on GPS Time System and adjust time form astronomical time is advanced, and the design software of measuring star, a system of measuring precision for the film theodolite in outside is developed, by which measuring precision for the film theodolite in outside become automated and easy. The problems of the impact precision measurement were studied. And this precision measurement may be applied to another photoelectric theodolite.
