Problems solved by technology

[0003] Satellite ground S-band signal transponders are usually designed with independent distributed chassis solutions, which are divided into uplink transponder transponders, downlink transponder transponders, downlink data transponders, and switch matrices. The operations are mainly based on front panel buttons and Manual attenuation control operation, configure an industrial computer to realize the monitoring and state storage functions of the above-mentioned equipment. According to the configuration of the main and standby modules, a total of 8 independent chassis equipment are required. The space occupied by the equipment is large, and the equipment needs to be replaced if there is a problem. , not conducive to rapid maintenance

Abstract

The invention relates to a satellite ground S band signal repeater comprising an uplink forwarding chassis used as an uplink of the satellite ground S band signal repeater; a downlink forwarding chassis used as a downlink of the satellite ground S band signal repeater; and a signal selection and monitoring switch chassis used for achieving monitoring signal switching selection and amplification attenuation functions of the satellite ground S band signal repeater, wherein each one of the uplink forwarding chassis, the downlink forwarding chassis and the signal selection and monitoring switch chassis is provided with a PXI controller and a plurality of modular PXI board cards held in a plurality of slots of the chassis. The satellite ground S band signal repeater according to the invention effectively solves the problems of non universality, poor extendibility, large volume and long maintenance time of the satellite ground S band signal repeater in the prior art.

Description

technical field [0001] The invention relates to a satellite ground S-band signal transponder, in particular to a satellite ground S-band signal transponder based on a PXI (PCI extensions for Instrumentation, PCI extension for instrumentation system) architecture. Background technique [0002] In the process of satellite ground remote testing, it is necessary to realize the functions of filtering and signal amplification and forwarding of the locally generated radio frequency signal through the S-band signal transponder. [0003] Satellite ground S-band signal transponders are usually designed with independent distributed chassis solutions, which are divided into uplink transponder transponders, downlink transponder transponders, downlink data transponders, and switch matrices. The operations are mainly based on front panel buttons and Manual attenuation control operation, configure an industrial computer to realize the monitoring and state storage functions of the above-ment...
