Problems solved by technology

[0006] The purpose of the present invention is to provide a design of a space-borne S-band dual-channel measurement and control receiver to solve the problem that the existing single measurement and control system transponder can only receive and process single system measurement and control signals, which cannot meet the needs of global networking and accurate measurement satellite systems asked questions
[0007] Another object of the present invention is to provide a design of a satellite-borne S-band dual-channel measurement and control receiver to solve the problem that the number of single-units and the volume and weight of the subsystems are greatly reduced when the satellite measurement and control subsystem requires the transponder to adopt dual-machine backup. additional questions

Abstract

The invention discloses a spaceborne S-band double-channel measurement and control receiver. The interior of the receiver is provided with a PM receiving channel, a DS receiving channel and a public S-band radio frequency front end in an integrated manner. The receiver employs an integrated circuit design, and two channels are serves backup for each other. The receiver can receive and process signals of two systems: S-band PM / PM measurement and control system and S-band direct spectrum spreading measurement and control system, and the received signals cannot interfere with each other, wherein the outputs are independent of each other. Compared with a single-system measurement and control receiver, the receiver extends the functions, improves the anti-interference capability and measurement precision, improves the reliability and safety, does not need to increase the number of units and the size and weight of a subsystem under the condition that a satellite measurement and control subsystem asks a responder to employ a double-machine backup, and saves the expenditure of a satellite system.

Description

technical field [0001] The invention relates to the design field of a satellite-borne measurement and control transponder, in particular to an S-band dual-channel measurement and control receiver. Background technique [0002] At present, TT&C transponders are widely used in earth-orbit satellite-to-ground TT&C systems. It is a channel to ensure the functions of distance measurement, speed measurement, orbit measurement, remote control and telemetry between the ground station and the satellite. Its components mainly include TT&C receivers and TT&C transmitters. machine. According to different carrier modulation systems, the commonly used measurement and control transponders mainly include phase modulation (PM / PM) system transponders and direct spread spectrum (DS) system transponders. [0003] The PM / PM measurement and control system has been developed for a long time, and there are a large number of ground stations supporting this system around the world, and it is widely ...
