Comprehensive positioning and navigation equipment for special vehicle with navigation aid lamps arranged quickly

Abstract

The invention discloses comprehensive positioning and navigation equipment for a special vehicle with navigation aid lamps arranged quickly, and relates to the technical field of positioning and navigation. Position information and advancing direction information of the special vehicle are comprehensively positioned through signals of the differential Beidou satellite receiver, the single-point Beidou satellite receiver, the side line camera, the inertial navigation module, the angle and angular velocity sensor, the laser altimeter and the like. Reliable and high-precision positioning and navigation support can be provided for implementation of tasks such as rapid arrangement of airport navigation lights. According to the invention, Beidou satellite signals and various sensor information are comprehensively utilized, the equipment has the advantage of high positioning and navigation precision, has various working modes which can be freely switched, and still has certain applicability under the conditions that differential Beidou satellite signals are unavailable and airfield runway sideline vision is unavailable.
