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...
