Satellite time service machine and navigation receiver testing station

The invention relates to a satellite time service machine and navigation receiver testing station, which comprises a testing control computer, wherein the testing control computer is connected with an oscilloscope through a USB (Universal Serial Bus)-GPTB (General Purpose Interface Bus) interface, and is connected with a tested receiver through a first USB-RS422 circuit; the testing control computer is connected with the control end of a relay module through a second USB-RS422 circuit, and is used for controlling the output state of the relay module and providing a power supply channel for the tested receiver; navigation data demodulated by the tested receiver are transmitted to the testing control computer through the first USB-RS422 circuit; the oscilloscope is used for comparing a 1PPS time service signal input from a port A and a standard 1PPS signal input from a port B at the frequency of one every second; the oscilloscope is used for transmitting the measured data to the testing control computer for processing through a USB-GPIB adapting wire; testing of multiple indexes of the product is finished by controlling the oscilloscope and each module through the testing computer, and data are recorded. The satellite time service machine and navigation receiver testing station has the beneficial effects that the testing time is saved, more useful data are read, the measured data are displayed in the forms of a trend curve graph and a statistical histogram in real time, and the data are accurate.
