Abstract: Study about the transformation relationship among different coordinates systems has been made to solve the problems in the application of GPS. The precision of the simplified coordinates transformation formula has been analysed. It was shown that the rational simplification is necessary and it will help to enhance the efficiency of the GPS system, for example, the vehicle navigation and real-time monitoring systems. An example and a feasible method to solve the unkown parameter are provided.

Key words: GPS geodetic coordinates, Gauss projection, coordinates transformation, GPS geodetic coordinates, Gauss projection
