An Introduction To The Adjustment OfAstro-geodetic Net Of The People's Republic Of China

Gu Dansheng  
: This paper describes briefly and in an all-round way the related techical problems in Chinese astro-geodetic net adjustment as a whole. 1. The configuration of Chinese astro-geodetic net and the scale entering for ad- justment as a whole. 2. The selection and orientation of the reference spheroid ; the astronomical observa- tion system: length standard; the computation of deflection of vertical and height anom- aly; the problem of adjustment carried out on the spheroid; the treatment of Laplace azi- muth in adjustment; the problem on an unified adjustment of triangulation and traverse of all classes as a whole. 3. The basic principle of adjustment by the method of conditional connection used for Chinese astro-geodetic net adjustment as a whole and some problems involved in the method of treatment; a method suitable for the solution of normal equations on a large scale by electronic computer.
