Derivationof Mathematical Equations to Calculate the Geographical Coordinates ofUnknown Position SituatedataDistance from the Observer Position Using GPS Data

Abstract

This research introduced the derivation of mathematical equationsto calculate the Cartesian and geographical coordinates of a site situated at a far distance from the observer position by using GPS data.The geographical coordinates (obs.,  obs.,hobs.) for observer position were transformed to Cartesiancoordinates(X obs., Y obs., Z obs.) of observer position itself.Then the Cartesian coordinates of unknown position mathematicallywere calculated from these calculated equations, and its transformedto geographical coordinates of (unk.,unk.)position.
