A Coordinate Transformation Algorithm for GPS Navigation and Positioning System

With the development of GPS navigation system, people rely on navigation and positioning system is also increasingly strong. Now the GPS system has become the world's most widely used navigation system, it is a user can provide global, all-weather real-time positioning information navigation system. Therefore, the research on GPS navigation is also more in-depth. This paper mainly studies the coordinate transformation algorithm in GPS navigation process. In the navigation process, the navigation system first transforms the coordinate system and converts the coordinates under the received 54 coordinate system into the coordinates in the local coordinate system. In this paper, we mainly study the Gaussian transformation model, and transform the coordinates of the earth's ellipsoid into plane coordinates according to the Gaussian transformation model, and then we can further transform the coordinates to obtain the easy-to-express plane coordinate.
