摘要
论述大连地磁台天文方位角的测量原理、方法及观测结果,在地磁观测室未封顶的条件下,能在观测墩直接观测北极星,避免比测墩转角换算等因素增加的观测误差,观测精度提高。
In this paper, the astronomical azimuth measurement principle, method and observation results at Dalian Geomagnetic Station are discussed. Due to Dalian Seismic Station under the condition of not capped, It is possible to directly observe Polaris on pier, avoided the meas- ure error increaded in the angle convertion in then measuring of pier. The observation accu- racy is improved.
