Abstract

The invention provides a remote sensing satellite data transmission product automatic testing system and method. The remote sensing satellite data transmission product automatic testing system comprises a PXI system controller which provides a real-time operating system for a whole PXI platform; a PXI module set which is connected with a PXI bus and provides a direct interface for a tested product; a PXI case which provides a stable mechanically structured platform and a reliable power supply and heat radiation system for the PXI system; and a piece of testing system software which cooperates with the PXI module set to realize corresponding functions and provides an interacting interface for a user. Based on universal PXI architecture design, the remote sensing satellite data transmission product automatic testing system overcomes the disadvantages of huge device scale, high construction difficulty and long period of an existing remote sensing satellite data transmission ground testing system.

Description

technical field [0001] The invention relates to the technical field of testing satellite digital transmission products, in particular to an automatic testing system for remote sensing satellite digital transmission products. Background technique [0002] Remote sensing satellite data transmission subsystem products are generally composed of data preprocessing equipment, baseband data processing equipment and radio frequency processing equipment, complete the processing work of payload data reception, preprocessing, access, formatting, coding, modulation, etc., and provide satellite payload data ground transmission channel. [0003] The satellite data transmission ground test system first needs to complete the inverse process of on-board processing, restore the received radio frequency signal to the original state of the payload data, and complete the signal quality evaluation of the data transmission process. In addition, when performing independent testing of subsystem pro...
