Application of Electronic Theodolite(T3000/T2000s) to Astronomical Surveying

ZHANG Chao, ZHENG Yong, XIA Zhiguo(Institute of Surveying and Mapping, Information Engineering University, Zhengzhou,450052,China)  
Theories of surveying an angle with electronic theodolite(T3000/T2000s) are introduced.Its communication with the computer and the delay time of surveying an angle with electronic theodolite are researched into. The characteristics and stability of the delay time in electronic theodolite's angular measurements are analysed. Utilization of electronic theodolite in the observation of astronomical longitude and altitude are put forward. Grade 1 observation of geodetic astronomy by using high precise electronic theodolite is realized.

2 Cheng Xuerong(Institute of Geodesy and Ceophysios Sinica Academia)A method is proposed to calculate 3 components of purterbed gravity by combiningthe terrestrial gravimetric data and sattlite altimetric ones,with the fictitious gravityanomalies and fictitious mass points as Intermediate mediums.Model computation of the above methods shows pretty good digital results.We findthat to get the same accuracy,the extent needed is much smaller when using our methodthan that when using Stokes' Fomula.For example,if we perform Stokes' integra-tion within concentric circles with radii of 4.4 km and 44 km respectively,we shallfind that the former is about1/25 of the latter; but the accuracy changes little whenusing our method in the above different areas.This shows its advantage.We concludethat it will be suitable for the calculation of 3 components of purterbed gravity.;A DISCRETE METHOD OF GEODETIC BOUNDARYVALUE PROBLEM[J];Acta Geodaetica Et Cartographic Sinica;1984-02
