Problems solved by technology

[0002] The existing GPS (Global Positioning System) test system adopts the test method system of antenna anechoic chamber or microwave anechoic chamber, which can only measure the positioning ability and signal strength of GPS under general environmental conditions, because it cannot simulate rural, plain and mountainous areas. Doppler, multi-path fading and multi-path interference conditions of positioning accuracy, receiving sensitivity, cold start hot start warm start the first positioning time, anti-interference and other performance conditions, can not make a comprehensive performance of GPS products Evaluation and improvement of GPS production quality and performance

Abstract

The invention relates to a GPS test system, comprising a main control device, wherein the main control device is connected with a channel simulator, an interference signal source device and a GPS signal source device, the interference signal source device and the GPS signal source device are connected with the channel simulator by a radio frequency line, and the channel simulator and the GPS signal source are connected to a test terminal through a radio frequency line. The GPS test system provided by the technical solution can accurately simulate various environments, can use a switch unit tosuperimpose different interference signals into the same channel, can intuitively confirm the sensitivity and the anti-interference performance of the GPS, and correctly judge the defects of the GPS.The test system can be repeated, the accuracy and measurement accuracy are high, the measurement speed is fast, and the safety performance and quality of GPS are effectively improved.

Description

technical field [0001] The invention relates to the technical field of communication equipment testing, in particular to a GPS testing system. Background technique [0002] The existing GPS (Global Positioning System) test system adopts the test method system of antenna anechoic chamber or microwave anechoic chamber, which can only measure the positioning ability and signal strength of GPS under general environmental conditions. Doppler, multi-path fading and multi-path interference conditions of positioning accuracy, receiving sensitivity, the first positioning time of cold start hot start warm start, anti-interference and other performance conditions, can not make a comprehensive performance of GPS products Evaluation and improvement of GPS production quality and performance. Contents of the invention [0003] The technical problem to be solved by the present invention is how to provide a GPS test system that can accurately simulate various environments, use the switch ...
