Control device for closed-loop star searching system and control method thereof

Abstract

The invention provides a device for controlling a closed-loop star-finding system and a control method thereof, which relate to the technical field of closed-loop satellite star-finding system. The signal output ends of a pitch motor sensor are respectively connected with the signal input ends of a pitch transmission mechanism and a paired star control module; the signal output ends of an azimuth motor sensor are respectively connected with the signal input ends of an azimuth transmission mechanism and the paired star control module, the signal output ends of a polarizing motor are respectively connected with a polarizing transmission mechanism and the paired star control module; the signal output ends of the paired star control module are respectively connected with the signal input ends of the pitch motor, the azimuth motor, the polarizing motor and a computer, and the signal output end of the computer is connected with the paired star control module; and the signal output ends of a GPS receiver and an electronic compass are respectively connected with the paired star control module. The device achieves aims of low cost, simple control, convenient operation, short time and high stability.

Description

technical field [0001] The invention relates to the technical field of a star-finding system for closed-loop satellites. Background technique [0002] Since the current domestic satellite-to-satellite systems all adopt the open-loop control principle and stepping motor transmission structure, the control system needs to know the pitch, azimuth and polarization position of the antenna and drive the pitch motor through the memory of the control chip. How many pulses of the module, azimuth motor drive module and polarization drive module to know the specific position, this method is difficult to control, mechanical errors, sudden power failure when the antenna is moving, and stepping motor lost steps will bring a lot of errors, which will cause a lot of errors to the satellite. The success rate and control bring inconvenience. Contents of the invention [0003] The object of the present invention is to provide a control device and control method of a closed-loop star-seeking...
