Abstract

According to the Beidou signal capturing method and system in the weak signal environment and the cloud platform provided by the embodiment of the invention, the corresponding mapping processing result can be determined by combining the Beidou intermediate frequency signal data and the pseudo code signal data and utilizing the first preset strategy; in this way, expansion and reduction processing of the signal data can be achieved through different mapping processing results so as to obtain the optimized signal corresponding to the Beidou intermediate frequency signal data to be processed, and due to the fact that the optimized signal is obtained according to the different mapping processing results, on one hand, the authenticity of the optimized signal can be guaranteed; and on the other hand, the integrity of the optimized signal can be ensured as far as possible, so that the signal capturing efficiency, quality and precision in a weak signal environment are ensured.

Description

technical field [0001] The present application relates to the technical field of Beidou signal processing, and in particular to a Beidou signal acquisition method, system and cloud platform in a weak signal environment. Background technique [0002] The development of science and technology has continuously improved people's quality of life. Taking navigation as an example, digital navigation technology has been widely used in daily production and life. Compared with the previous paper map navigation, digital navigation technology is more intelligent and more convenient. At present, Beidou navigation technology has been gradually applied in various scenarios. For some scenarios, the signal acquisition ability of Beidou navigation technology still has some defects. For example, how to ensure the quality and accuracy of navigation signal acquisition in a weak signal environment is a technical problem that needs to be improved at present.
