Satellite Service Unit Controller

Abstract

The invention discloses a satellite service unit controller. The controller involves a pulse sequence, a module address, a monitoring and control frame signal, a command frame signal, a unit monitoring and control instruction, instruction output voltage control, a command area selection jumper 0, a command area selection jumper 1, a command area selection jumper 2, a Y8-Y23 memory / status jumper, aY24-Y31 memory / status jumper, telemetry data input, a 72-bit control frame, and the like. According to the satellite service unit controller of the invention, a traditional method applied to a satellite adopts a circuit board to realize the collection of various telemetry data and the generation of remote control commands, as a result, many defects can arise, while, with the satellite service unit controller adopted, the defects can be eliminated; many functions can be integrated on one chip, and therefore, the technical problem of the universalization of the generation of satellite remote commands and the collection of various telemetry data can be solved; the functional density of the satellite service unit controller is high; compared with the weight of the cable networks of similar satellites in the prior art, the weight of the cable network of a satellite using the controller of the invention can be reduced by more than 70%; since the weight of the whole satellite is reduced, launching cost is reduced; and the controller has been successfully applied to a satellite of a certain model in China and has achieved good economic benefits.

Description

technical field [0001] The invention relates to a controller, in particular to a satellite service unit controller. Background technique [0002] A certain type of satellite implements power supply and distribution, control, and measurement for each stand-alone machine in accordance with the principle of proximity to the south, north, and bilge, and implements the power distribution, control, and measurement of the same stand-alone machine on the same module. Traditional satellites complete these functions completely. The use of an independent stand-alone unit brings problems such as many measurement signals of the stand-alone unit and complicated cable connections, and the weight of the stand-alone unit and the cable network is relatively large. This type of satellite is under pressure to reduce weight. It is necessary to increase the functional density of the stand-alone unit, optimize the information flow, and reduce the weight of the cable network. , can not be solved by...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a satellite service unit controller, which can overcome the shortcomings of the traditional method of using circuit boards on satellites to realize multiple telemetry data collection and remote control command generation, and integrate its functions into a chip. It solves the general technical problems of satellite telemetry and remote control command generation and multi-type telemetry data collection, and has high functional density. Compared with the weight of the entire satellite cable network of similar satellites, the use of this controller can reduce the weight of the cable network by more than 70%. The weight of the star makes the launch cost lower
