Problems solved by technology

[0002] In complex signal environments, such as: urban canyons or indoor and outdoor switching positioning scenarios, Global Navigation Satellite System (GNSS) signals often face occlusion, attenuation or multi-path, resulting in signal quality degradation and corresponding channel Tracking issues such as deteriorating conditions
If the observations of the channel corresponding to the signal are used for navigation calculation or information fusion in the vector structure, it will have a negative impact on the navigation results and the tracking of other channels

Abstract

The embodiment of the invention relates to the field of communication, and discloses a signal quality monitoring method and device, electronic equipment and a storage medium, so as to solve the problem that GNSS signal quality cannot be accurately monitored in a complex signal environment. The method is applied to a GNSS signal receiver, the GNSS signal receiver comprises more than two signal tracking channels, each signal tracking channel is used for receiving a GNSS signal, and for each signal tracking channel, the method comprises the following steps: obtaining a carrier-to-noise ratio estimation value, a Rice K factor estimation value and spreading chip shape monitoring data of the GNSS signal; and acquiring a monitoring result of the GNSS signal quality according to the carrier-to-noise ratio estimation value, the Rice K factor estimation value and spreading chip shape monitoring data.

Description

technical field [0001] Embodiments of the present invention relate to the field of communications, and in particular, to a method, device, electronic device, and storage medium for monitoring signal quality. Background technique [0002] In complex signal environments, such as urban canyons or positioning scenarios for indoor and outdoor switching, Global Navigation Satellite System (GNSS) signals often face occlusion, attenuation, or multi-path conditions, resulting in reduced signal quality and corresponding channels. Tracking of worsening conditions, etc. If the observation of the corresponding channel of the signal is used for navigation calculation or information fusion in the vector structure, it will have a negative impact on the navigation results and the tracking of other channels. Therefore, how to accurately monitor the quality of GNSS signals in real time under complex signal environments has become an urgent problem to be solved. SUMMARY OF THE INVENTION [...
