Real-time Beidou satellite signal acquisition and analysis system

Abstract

The invention discloses a Beidou satellite signal acquisition and analysis system, which develops a satellite signal automatic detector based on a Beidou module and realizes automatic acquisition anddetection of information such as satellite signal coverage, satellite signal intensity and equipment power consumption in a scientific ocean operation sea area. A Beidou data transmission system is established. The safe transmission of secret-related information and data of the scientific number is realized. A land-based data receiving management software system is constructed. The automatic storage and wareshell of satellite signal quality, intensity and other information in a scientific number operation area are achieved. The visual display of related data is achieved in combination with a GIS geographic information system.

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 uses the foreign Iridium system, the submarine buoy observation data needs to be forwarded to the domestic server after passing through the foreign Iridium star server. This process has two potential risks: (1) The real-time data of my country's deep-sea submarine Transmission to foreign Iridium servers, this process increases the risk of data being intercepted by the other party; (2) forwarding from foreign servers to domestic servers increases the risk of data loss. In order to test the technical indicators, overall performance and system reliability of real-time communication submersible targets, the foreign iridium satellite system is temporarily used for data transmission, because the test sea area is located in internationa...

AI Technical Summary

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
