Theodolite type laser coarse pointing mechanism

Abstract

The invention discloses a theodolite type laser coarse pointing mechanism which comprises a pitch axis assembly and a pitch auxiliary supporting assembly which are installed on the two side walls of aU-shaped frame respectively. An azimuth axis assembly penetrates through the bottom face of the U-shaped frame to be installed, the two ends of the load are respectively connected with the pitching shaft assembly and the pitching auxiliary support assembly, and the two ends of a pitch axis locking arm are respectively connected with the load and a pitch axis locking and releasing device. A coil part and an armature part of a parking electromagnet are respectively connected with the pitch axis locking and releasing device and the pitch axis locking arm, the two ends of the azimuth axis lockingarm are respectively connected with the U-shaped frame and the azimuth axis locking and releasing device, and a light path assembly is arranged at the outer side of the pitching auxiliary supportingassembly. According to the invention, the problems of low data transmission rate, low tracking precision, poor long-distance communication quality, slow response speed, low tracking bandwidth, much signal energy dissipation, larger space size, high transportation and emission cost and the like of a traditional radio frequency antenna turntable communication device are solved.

Description

technical field [0001] The invention belongs to the technical field of laser communication, and in particular relates to a laser coarse pointing mechanism for a latitude and longitude ceremony. Background technique [0002] Between satellites, space stations, planetary probes and other spacecraft in space, as well as between spacecraft and the earth, data needs to be transmitted to each other for communication. At present, the communication between spacecraft or with the earth mainly adopts the traditional radio frequency communication mode. The radio frequency antenna is installed on the turntable as a load, and the communication between spacecraft is realized through the orientation or dynamic rotation tracking of the turntable. [0003] The traditional radio frequency antenna turntable communication device mainly has the following problems: [0004] First, the data transmission rate of the radio frequency antenna turntable communication device can no longer meet the need...
