| Abstract: | A new methodology for precise geoid determination with finest local details based on ellipsoidal approximation is presented.This methodology is formulated through the "fixed_free two_boundary value problem" based on the observable of the type modulus of gravity intensity,gravity acceleration and gravity potential at the GPS positioned stations,with support of the known geoid's potential value,W 0 |
