Problems solved by technology

[0003] The traditional ground test equipment for the measurement and control system can only meet the basic test requirements of the measurement and control system, and can only perform single-channel testing. Most of them are purchased from abroad, the cost is high, and the technical service is not timely. Functions are modified locally to meet differentiated test requirements, resulting in low test efficiency and high test costs, which restricts the development of the commercial satellite industry

Abstract

The invention discloses a satellite measurement and control ground integrated test system based on PXI architecture. The system comprises a PXI case which comprise a plurality of slot positions; a master control board which is integrated on the PXI case and is used for operating LabVIEW upper computer software; a signal transceiving board which is integrated on the PXI case and is used for supporting generation and reception of 65MHz-6GHz full-band radio frequency signals; and an FPGA board which is integrated on the PXI case and is used for processing baseband telemeasuring data in real time.One or more sets of signal transceiving boards and FPGA boards are integrated on the PXI case. The measurement and control ground integrated test system supports intermediate frequency full digital processing based on a software radio platform. The signal transceiving board carries out data transmission with the FPGA board in a peer to peer mode. The master control board carries out data transmission with the signal transceiving board and the FPGA board in a queue form. According to the satellite measurement and control ground integrated test system based on the PXI architecture provided by the invention, multichannel test is realized, and free switching can be realized between a USB measurement and control system and a spread spectrum measurement and control system.

Description

technical field [0001] The invention relates to the field of satellite test equipment, in particular to a satellite measurement and control ground comprehensive test system based on a PXI framework. Background technique [0002] The measurement and control system is mainly responsible for the transmission of remote control and telemetry signals between the satellite and the ground station, as well as the distance measurement and speed measurement of the satellite by the ground measurement and control network. Since the measurement and control system is the only way for the ground to control and exchange data with the satellites in orbit, it must have a high degree of reliability. Therefore, before the satellite is launched, it is necessary to rely on ground test equipment to strictly test the measurement and control system. Test, the test indicators of the measurement and control system are diverse, and the test process is complicated, so test equipment is required to meet d...
