Real-time Beidou satellite signal acquisition and analysis system

Abstract

The invention discloses a Beidou satellite signal acquisition and analysis system, develops an automatic satellite signal detector based on a Beidou module, and realizes automatic acquisition and detection of information such as satellite signal coverage, satellite signal strength and equipment power consumption in the oceanic operation area of ​​the Science number; The data transmission system realizes the safe transmission of classified information and data of the Science number; builds a land-based data reception management software system to realize the automatic storage and storage of information such as the quality and strength of satellite signals in the operation area of ​​the Science number, and realizes related information in combination with the GIS geographic information system. Visual display of data.

Description

technical field [0001] The invention belongs to the technical field of satellite communication, and relates to a real-time Beidou satellite signal acquisition and analysis system. Background technique [0002] Since the satellite communication system adopts the foreign iridium star system, the observation data of the submerged target needs to be forwarded to the domestic server through the foreign iridium star server. Transmission to a foreign iridium server increases the risk of data being intercepted by the other party; (2) forwarding from a foreign server to a domestic server increases the risk of data loss. In order to test the technical indicators, overall performance and system reliability of the real-time communication submersible target, the foreign iridium system is temporarily used for data transmission, because the test sea area is located in the international sea area, and the deep-sea real-time data at this stage only serves scientific research and climate forec...

Problems solved by technology

However, the real-time Western Pacific Submarine Observation Network will focus on the application requirements of national security. In this case, the real-time transmission of deep-sea data can no longer rely on foreign satellite communication systems, otherwise foreign hostile forces can steal or tamper with data at any time. The situation may also interrupt the satellite transmission and seriously damage the national security of our country, so it is necessary to ensure the safety, autonomy and controllability of the deep sea real-time data transmission
