Embodiment Construction

[0024] The present invention will be further described below in conjunction with the drawings.

[0025] A method for real-time navigation satellite signal quality monitoring. The method uses a high-gain antenna to receive navigation satellite signals, collects, stores, and preprocesses the signals through a signal processing board, and finally completes real-time The navigation data is played back to realize the reproduction and repeated monitoring of the navigation signal. It includes the following steps:

[0026] (1) Use a high-gain antenna to receive navigation satellite signals and transmit the navigation satellite signals to the signal processing board;

[0027] The high-gain antenna provides high gain, improves the signal-to-noise ratio of the navigation signal, and ensures that the signal quality monitoring function can be realized. Reference figure 1 Shown.

[0028] (2) Use the signal processing board to sample and quantize the navigation satellite signal and divide it into ...

Abstract

The invention discloses a real-time monitoring method of navigation satellite signal quality. A high-gain antenna is used for receiving a navigation satellite signal; on the basis of a real-time collection storage processing platform and a high-speed data link, a real-time monitoring method of navigation satellite signal quality is provided by using a signal processing technology, so that real-time monitoring of navigation signal quality is realized for the first time. Therefore, the method has the important significance in navigation system establishment.

Description

Technical field [0001] The invention relates to a satellite navigation system, in particular to a real-time navigation satellite signal quality monitoring method, which realizes the real-time monitoring of the navigation satellite signal quality. Background technique [0002] Since the signal processing involved in the monitoring of the navigation signal quality is more complicated and the amount of calculation is large, in the current satellite navigation system technology, the signal quality monitoring function adopts the post-processing method, which is to store the data for a period of time and then use Software to post-process the stored data. The processing speed of the post-processing method is very slow, the time period of the navigation signal that can be monitored is relatively short, the quality of the navigation signal cannot be monitored in the whole process, and it has no real-time processing capability. Summary of the invention [0003] The purpose of the present i...
