Abstract

The invention discloses a portable satellite navigation device tester system which integrates a variety of testing equipment with the single function, has simple control procedures, and reduces the professional requirements for the test personnel and the phenomenon of return-to-factory maintenance, to avoid time and money waste. The design and implementation of the system adopts a test mode of combining the "signal source + reference device", "signal source + device under test", "antenna + reference device" and "antenna + device under test" four modes to make a comprehensive assessment of the performance of the device under test. The system designs and realizes wide voltage power supply suitable for a variety of devices under test, monitors the working voltage and current of the device under test, and performs hardware protection measures in the abnormal conditions, so as to ensure the security of the tester, the device under test and the test personnel.

Description

technical field [0001] The invention relates to a portable satellite navigation equipment tester system. Background technique [0002] For satellite navigation terminals that have been equipped in the system or on the carrier and are in use, there is currently no convenient and fast test and maintenance method. Generally, the following two solutions are adopted: 1. Remove the navigation terminal and send it back to the manufacturer or laboratory for testing; 2. Carry a series of equipment such as power supply, multimeter, notebook computer, test software, test cable, standard receiver and antenna to test the navigation terminal on site. However, the above solutions have the following drawbacks: the first involves the transportation of navigation terminals, which is time-consuming; the second requires carrying a variety of instruments and equipment, and the testing process is complicated. Contents of the invention [0003] The present invention provides a portable satellit...
