Abstract

The invention relates to the field of GNSS module testing, and discloses a GNSS module automatic test system comprising a test clamp, a satellite signal simulator, a control server, an oscilloscope and a frequency spectrograph. The satellite signal simulator, the oscilloscope and the frequency spectrograph are connected with a GNSS module to be tested via the test clamp. The control server is respectively connected with the test clamp, the satellite signal simulator, the oscilloscope and the frequency spectrograph. Automatic test control based on the GNSS module is realized. Multiple types of test equipment are integrated in the system so that accurate testing and calibration of multiple key performance parameters are realized.

Description

technical field [0001] The invention relates to the field of GNSS module testing, in particular to a GNSS module automatic testing system. Background technique [0002] As GPS technology has been gradually popularized, many designs focus on improving the related characteristics of GPS, such as: reducing power consumption, finding weak satellite signals, faster retrieval times, more accurate positioning functions, etc. Most of the current GNSS module automatic test systems only support a single constellation GPS, but lack support for multiple pairs of Beidou COMPASS; the system is simple, the test item is single, and lacks support for performance indicators such as sensitivity and positioning accuracy; the traditional C / S mode There are many restrictions in use, and the degree of monitoring automation is not high. It can be seen that there are still many shortcomings in the existing GNSS automatic test system. Contents of the invention [0003] The invention provides a GN...
