Abstract

The invention discloses a on-board relay SMA terminal system supporting short message, which comprises a satellite-borne SMA transponder, an SMA power amplifier, an SMA duplexer and an SMA antenna. The SMA transponder receives the remote control signal, carries out the frequency conversion, the demodulation, the decoding and the descrambling, obtains the remote control data and sends it to the back end for processing; The telemetry data are encoded, scrambled, modulated and frequency-converted, and sent to SMA power amplifier for signal amplification. The SMA power amplifier amplifies the telemetry signal sent by the SMA transponder according to the requirements of the backward communication link. The SMA duplexer filters and isolates the telemetry signal and the telecontrol signal. The SMA antenna receives the telecontrol signal from the second generation relay satellite and transmits the telemetry signal from the SMA power amplifier to the second generation relay satellite through the space channel. The invention can support bi-directional and fast communication between the satellite and the second generation relay satellite, can send short message telemetering for recording important information of the satellite for a long time, has high reliability, simple structure and simple use.

Description

technical field [0001] The invention relates to the aerospace field, in particular to a spaceborne relay SMA terminal system supporting short messages. Background technique [0002] my country's first-generation and second-generation relay satellite SSA measurement and control links use a parabolic antenna to communicate with the user star. Before communication, the antenna needs to be rotated to point to the user star to establish a communication link. The link establishment process takes a long time. The second-generation relay satellite SMA measurement and control link uses a phased array antenna to communicate with the user star, and can establish a communication link with the user star through electronically controlled beam pointing, and the link establishment process is fast. [0003] A space-borne relay SMA terminal system supporting short messages proposed by the present invention can quickly realize the communication between the user satellite and the relay satellit...
