Abstract

The invention discloses a multifunctional measurement and control and data distribution terminal for improving the real-time performance of data transmission, characterized by comprising a telecontrolcommand receiving module, a telemetry signal transmitting module and a data distributing module, wherein the telecontrol command module receives telecontrol signals of a ground monitoring and controlstation or a relay satellite, completes carrier demodulation, despreading, descrambling and decrypting processing, and transmits the processed telecontrol information code to an on-board computer; The telemetry signal transmitting module and the data distribution module are fused together to form a fusion module. The invention completes the fusion of the satellite telemetry data and the broadcastdistribution data to the user at the data level, which greatly reduces the weight, layout and power consumption requirements of the whole satellite, and improves the universality, reliability and flexibility compared with the traditional independent scheme of the satellite-borne TTC stand-alone machine and the data distribution terminal.

Description

technical field [0001] The invention relates to the field of satellite systems, in particular to a multifunctional measurement and control and data distribution terminal that improves the real-time performance of data transmission. Background technique [0002] When a satellite is operating in space, it needs to receive remote control commands from the ground or relay satellites and send telemetry signals to the ground or relay satellites, and also needs to distribute key data to ground users. At present, telemetry data and broadcast distribution data to users are generally sent separately, which greatly increases the size and weight of the satellite, and the real-time performance of communication is not high. Contents of the invention [0003] In view of the current domestic satellite function intensification and miniaturization development needs, the present invention designs and forms a unified and general-purpose spaceborne measurement and control and data distribution...
