Abstract

The present application discloses a device for rapidly detecting the performance of a satellite navigation terminal installed on a carrier platform, comprising: a real-time receiving terminal for the sky, which is used to receive real satellite signals in real time and obtain corresponding time information and ephemeris files through calculation and analysis; The equipment generates simulation control parameters according to the preset test scene and the time information and ephemeris files, and compares the test results output by the satellite navigation terminal under test with the simulation control parameters, and completes the simulation control parameters on the carrier platform in batches. Satellite navigation performance detection of the satellite navigation terminal under test; satellite navigation detection signal simulation equipment, which is used to generate detection signals according to time information, ephemeris files, and simulation control parameters; transmitting antennas are used to send detection signals to the test site. All satellite navigation terminals under test installed on the carrier platform broadcast. The application effectively simplifies the testing process, has high testing efficiency, low construction cost, reduces testing cost, and satisfies various testing usage requirements.

Description

technical field [0001] The present application relates to the technical field of detection of satellite navigation terminals under test, and in particular, to a device for rapidly detecting the performance of a satellite navigation terminal under test installed on a carrier platform. Background technique [0002] With the development of science and technology, carrier platforms including automobiles and small aircraft have been transformed into mass products consumed by thousands of households. Continuous, real-time and accurate positioning is one of the important guarantees for the safe driving of carrier platforms. The global satellite navigation system has the characteristics of global and all-weather. In most cases, the motion platform adopts the global satellite navigation system, but in some special areas, other methods are needed for auxiliary positioning. Therefore, it is necessary to conduct a comprehensive test of the performance of the satellite navigation termina...
