| Abstract: | The method of fast astro-geodetic orientation by observing the constellation stars is put forward in this paper.With the help of software Stellarium,the constellation-star database is established.Considering the main error sources in astronomical orientation,the tactic of choosing star,which can improve the orientation precision,is researched.According to the practical surveying experiment,inner precision of orientation by surveying constellation stars can be superior to 0.5″,and outer precision can be superior to 1.0″. |
