preparation of a geodetic calculator for earth gravity field computation

Although, nowadays detennination of the earth gravity field parameters for different applications is a usual matter for geodesy and geophysics sdentists, but in many cases because of the variety in strucbJre of programs and correction, oonsiderable discrepancy in results were observed. Also most of them are not user-friendly and applicant need to familiar with program structure and related formula. So base on this demand we attempted and in consideration of all scientific corrections, have produced a geodetic calculator for computation of the earth gravity field mmponents at interesting point
