To accomplish the calculation in base-point net conjunction measurement using VB programming

All but the topographic correction is involved in the whole program for calculating gravity in this paper and calculation methods for the parameters initialization of the survey area and base-point conjunction measurement (three-way loop observation) are introduced firstly. The initialized file GDW. CSH is created in calculation methods for the parameters initialization of the survey area (Various functions of procedures all read related the parameters within that document) The precision of base-point conjunction is calculated and the absolute gravity of each base-point is given by balancing the conjunction measurement in base-point conjunction measurement.
