Abstract

The invention provides a satellite transponder inherent time delay automatic testing device and method. The testing device comprises an automatic testing computer, a time delay measurement terminal, an up frequency converter, a down frequency converter, a 2*4 radio frequency matrix, a testing frequency converter and a satellite transponder, wherein uplink intermediate frequency range finding signals are converted into uplink radio frequency range finding signals via frequency conversion through the up converter, the uplink radio frequency range finding signals are sent to the satellite transponder via the 2*4 radio frequency matrix, down link radio frequency range finding signals sent by the satellite transponder are sent to the down frequency converter via the 2*4 radio frequency matrix and are then converted into down link intermediate frequency range finding signals, the down link intermediate frequency range finding signals are sent to the time delay measurement terminal, time delay data of the satellite transponder is calculated via the time delay data measurement terminal and sent to an automatic testing computer, the satellite transponder is replaced with the testing frequency converter as a testing object, time delay data of a ground system is calculated via the time delay measurement terminal, and inherent time delay of the satellite transponder can be obtained via the automatic testing computer. Via the satellite transponder inherent time delay automatic testing device and method, automation testing is realized, testing data consistency is improved, and good universality is realized.

Description

technical field [0001] The invention relates to a satellite transponder system, in particular to an automatic test device and a test method for the inherent time delay of a satellite transponder. Background technique [0002] When the satellite is in orbit, the ground station transmits the uplink radio frequency ranging signal to the satellite, the satellite transponder receives the uplink radio frequency ranging signal, broadcasts the downlink radio frequency ranging signal to the ground, the ground station receives the downlink radio frequency ranging signal, and calculates the distance between the ground station and the The distance to the satellite. The position of the satellite relative to the earth can be determined by combining the satellite-ground distances of multiple ground stations. [0003] As an electronic device, the satellite transponder needs to consume a certain amount of processing time from receiving the uplink radio frequency ranging signal to sending th...
