Navigation system and method using sensor fusion with ions and gps

The present invention relates to a navigation system and method for the recognition of the platform position, velocity, and moving direction to fuse and IONS GPS sensor. Measured with a GPS module to measure the absolute coordinates of the platform, relative position of the inertial sensor and an optical sensor the platform, including the speed and the moving direction from the information received navigation system from a satellite according to an embodiment of the invention for this purpose IONS module and by a control unit for the fusion to the absolute of the measurement platform in the GPS module coordinates and the relative coordinates of the measuring platform in IONS module, speed, and traveling direction information to determine the platform's position, speed and travel direction, It characterized in that the GPS module determines the position of the platform, the speed and the traveling direction even when not receiving the signal from a satellite for a predetermined time.
