Abstract
The mobile unit equipped with the satellite positioning system augmented by the laser positioning system is disclosed. The usage of the satellite positioning system allows the user to determine the coordinate of the laser reflectors prior to the range measurements. The range measurements are performed by the navigational computer using the laser scanning and rotating beam to obtain the range data between the mobile unit and a plurality of laser reflectors, and using the satellite positioning system to obtain the range data between the mobile unit and a plurality of visible navigational satellites. The obtained range data and the laser reflector coordinate data allows the user to perform the navigation of the mobile unit.
