Relay Satellite Arrowborne User Terminal System Equipment

Abstract

A relay satellite rocket-borne user terminal system equipment disclosed in the present invention aims to provide a user terminal with high code rate and low cost. The present invention is realized through the following technical scheme: the rocket data acquisition module The space-based status information and forward commands of the module, the rocket data integration module sends the telemetry data stream to the relay measurement and control terminal module; the Ka-band phased array antenna module receives the beam pointing angle information and return telemetry sent by the relay measurement and control terminal module Information, send antenna status information and forward remote control instructions to the relay measurement and control terminal module; the relay measurement and control terminal module sends the telemetry data stream to the baseband signal processing module by receiving the telemetry data stream from the rocket, and calculates the beam pointing angle information and Ka radio frequency signals are sent to the Ka frequency phased array antenna module to radiate the signal to the relay satellite to complete the transmission of the relay satellite return link signal; together frame the space-based status information and report it to the rocket data acquisition unit.

Description

technical field [0001] The present invention and a relay satellite arrow-borne user terminal system equipment are particularly suitable for relay satellite arrow-borne user terminal system equipment for relay satellite system (TDRSS) communication. Background technique [0002] The relay satellite space-based measurement and control system is a measurement and control communication system that uses geostationary satellites (Skylink satellites), ground stations and user terminals for data relay. It mainly realizes two functions: one is tracking, telemetry and remote control of the aircraft; the other is data relay. The telemetry data and application data to be transmitted by the aircraft to the ground are first sent to the relay satellite through the S-band and Ku / Ka-band inter-satellite links, and the relay satellite then forwards it to the ground terminal station in the Ku / Ka-band, and then transmits it to the ground terminal station in the Ku / Ka band. The terminal station...
