Abstract

The invention discloses a vehicle-mounted azimuth transfer aligning device, which comprises a collimator, a differential GPS satellite directional device main antenna, a differential GPS satellite directional device slave antenna, a pentaprism device, a left-missile-borne inertial group target prism, and a right-missile-borne inertial group target prism. The differential GPS satellite directionaldevice slave antenna is fixed at the front end of a launch vehicle erecting frame; the a differential GPS satellite directional device main antenna is fixed at the tail end of the launch vehicle erecting frame; and the collimator and the pentaprism device are installed at an erecting arm of the middle part of the launch vehicle. The collimator is capable of aligning and collimating a right-angle prism of the differential GPS satellite directional device slave antenna as well as aligning and collimating the left-missile-borne inertial group target prism and the right-missile-borne inertial group target prism by the pentaprism device. Therefore, accurate alignment of azimuths of the left missile and the right missile can be realized.

Description

Technical field [0001] The invention relates to the technical field of missile launch systems, and specifically refers to a vehicle-mounted azimuth angle transfer alignment device and method. Background technique [0002] Launch vehicle weapon systems are widely used in modern warfare because of their mobility, concealment, and rapid response capabilities. At present, most launch vehicle weapon systems use strapdown inertial navigation systems for navigation on the missile. The strapdown inertial navigation system needs to complete initial alignment before starting navigation, that is, load information such as initial azimuth angle. [0003] Traditional vehicle-mounted azimuth transfer alignment uses high-precision vehicle-mounted inertial positioning and orienting equipment to complete north seeking, and uses a collimator to aim at the inertial group on the missile and the vehicle-mounted positioning and orienting equipment to complete azimuth transfer alignment. In this m...
