:
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.
