Abstract
In this paper derives a set of formulas of solving the Direct and Inverse Geodetic Problems with long distance from the chord of the ellipsoid through the rectangular space coordinate system of tanget plane.The theory is closed.The formulas are simple shut and fit in with calculation of electronic calculator.This paper extends formulas about reduction to help practical work.
