Abstract

The invention provides an upper injection receiving processor simulator of a navigation satellite. The upper injection receiving processor simulator of the navigation satellite comprises an analog signal processing unit and a digital signal processing unit, wherein the analog signal processing unit is used for performing down-conversion on an upper injection radio frequency signal to an analog intermediate frequency signal by completing radio frequency signal down-conversion, digital-to-analog conversion and data transmission, then converting the analog intermediate frequency signal into a digital intermediate frequency signal, and transmitting the digital intermediate frequency signal to the digital signal processing unit after packaging the digital intermediate frequency signal; and thedigital signal processing unit is used for receiving the digital intermediate frequency signal based on GPU operation, and processing the digital intermediate frequency signal so as to simulate the receiving of an uplink injection signal when a satellite operates.

Description

technical field [0001] The invention relates to the technical field of navigation satellite ground simulation, in particular to a GPU-based simulator of a navigation satellite upvoting receiving processor. Background technique [0002] The satellite simulator is used to represent the state of the space segment to carry out the test verification task of the navigation system. [0003] The above note: the receiving processor simulator is one of the important components of the satellite simulator, its main function is to receive the uplink injection / satellite time synchronization signal sent by the ground operation control (operation control verification subsystem) and complete the precise time comparison measurement , and transmit the measurement results back to the ground for two-way time synchronization between the satellite and the ground; demodulate the navigation information and parameters from the uplink injection signal, and send the information and parameters to the na...
