Hangzhou Geomagnetic Observatory, azimuth, testretest
- 摘要:
- 通过实际观测,描述了杭州地磁台方位角的检验结果，通过复测检验有两点认识：一种新技术新方法的应用，须经过不同方法的严格比较检验，验收合格后方可推广应用；如果采用简接法测定观测墩的方位角，其精度不完全决定于天文或GPS的观测精度，在很大程度上取决于水平角的观测精度。为此建议用此法测定观测墩的方位角，须有合理的观测程序和严密的观测技术，与此同时，尚须具备高于方位角精度要求的高精度精密光学经纬仪。
This paper describes the test results of the azimuth from actual observation of Hangzhou Geomagnetic Observatory. The test results suggest that, firstly, the active popularization on application must betaken a qualified acceptance through a comparison of different approaches to retest. And secondly, if azimuth of observation pier is determined by indirect methods, the azimuth accuracy will largely depend on the accuracy of horizontal angle observation, not only the accuracy of astronomical or GPS observation, so this paper suggest determination of azimuth of observation pier must have reasonable observation procedures, strict observation techniques, and highprecision optical theologize that higher than the azimuth accuracy.
