Abstract

The invention discloses a shelf satellite borne transponder. The shelf satellite borne transponder comprises a radio frequency transceiver module, an intermediate frequency processing module, a secondary power supply module, a duplexer, a relay receiving filter; wherein the radio frequency transceiver module is used for receiving and transmitting radio frequency signals to the ground or to the relay; the intermediate frequency processing module is used for the A / D conversion of received signals, the D / A conversion of reference signals, the acquisition and tracking of pseudo codes and carriers,and the signal processing of channels; the secondary power supply module is used for power supply filter, voltage conversion and transponder switch execution; the diplexer is used for the filtering processing of ground measurement and control radio frequency receiving signals and radio frequency transmitting signals; and the relay receiving filter is used for preselected filtering of relay measurement and control radio frequency receiving signals. According to the shelf satellite borne transponder disclosed by the invention, a unified hardware platform is adopted; and the purposes of general-purpose design, mass production without considering the models and shelf supply can be achieved through changing different software settings and replacing the diplexer and relay receiving filter withdifferent frequency points.

Description

technical field [0001] The invention belongs to the technical field of aerospace measurement and control communication, and in particular relates to a shelf-type spaceborne transponder. Background technique [0002] The transponder plays an extremely important role in aerospace measurement and control. It receives the ground uplink (relay forward) remote control signal and ranging signal, completes demodulation, despreading, ranging, and speed measurement functions; completes modulation, amplification, and forwarding downlink. Telemetry signal and downlink measurement signal. [0003] In the past, it was necessary to customize different transponders to meet the needs of different types of satellite missions. Not only were the costs very high, but the development cycle was also very long. Since the transponder is a traditional aerospace product, and the functions of receiving and transmitting are relatively fixed, it is completely possible to design a unified hardware platfo...
