Abstract

The invention provides a system for detecting dynamic range of a satellite navigation signal. The system comprises a satellite navigation signal simulator, a frequency meter, a frequency automatic collecting device and a dynamic range analysis and calculating module. The system for detecting the dynamic range of the satellite navigation signal is utilized. The invention also provides a method for detecting the dynamic range of the satellite navigation signal; on the basis of satellite navigation signal simulator working principle and Doppler effect, a radio frequency signal received by a receiver under different dynamic environments can be simulated in real time, the method for detecting the dynamic range of the satellite navigation signal is analyzed at the aspects, such as speed, acceleration and jerk, a dynamic range detecting platform is built, a specific testing scheme is formed, and the experiment is conducted to verify the correctness, practicality and effectiveness of the testing method. The testing method has the advantages that the simplicity, convenience and reliability are realized, and the dynamic range of the satellite navigation signal can be correctly detected in the simulating environment.

Description

technical field [0001] The invention relates to the technical field of satellite navigation, in particular to a dynamic range detection system and detection method of satellite navigation signals. Background technique [0002] With the construction of the Beidou satellite navigation system, satellite navigation, an emerging technology, is increasingly favored by all walks of life, and satellite navigation receivers are also widely used. Since satellite navigation receivers are mainly used in the fields of navigation and aviation speed measurement, high-precision surveying and mapping, etc., the accuracy and reliability of the output measurement data are very important. The satellite navigation simulator provides signals for high-precision measurement of satellite navigation receivers and other equipment. According to specific test requirements, a variety of different simulation scenarios are generated and run to test and verify satellite navigation receivers. Therefore, sate...
