Research and early warning platform for influence on navigation signals caused by solar radio burst, and method of research and early warning platform

Abstract

The present invention discloses a research and early warning platform for influence on navigation signals caused by solar radio burst, and a method of the research and early warning platform. The research and early warning platform comprises a solar radio flow monitoring part, a navigation satellite signal monitoring part and a computer; the solar radio flow monitoring part comprises a radio antenna, an analog receiver system, a calibration system, more than three power-voltage convertors and a data acquisition device; the navigation satellite signal monitoring part includes a navigation antenna and a navigation signal receiver; the solar radio flow monitoring part realizes precise calibration of multi-channel solar radio flow through real-time monitoring on solar radio flow and switching of a noise source, so as to judge whether a solar radio burst event occurs; the navigation satellite signal monitoring part is used for recording information such as current signal quality; and based on solar radio flow data and navigation signal quality data, influence on signal quality caused by the solar radio burst can be judged.

Description

technical field [0001] The invention belongs to the field of satellite navigation measurement and control, and in particular relates to a research, an early warning platform and a method for solar radio burst interference navigation signals, which are applicable to the early warning solar radio burst interference navigation communication field. Background technique [0002] The sun is the closest star to the earth. While transmitting light and heat to the earth, its activities also affect human production and life in various aspects, as well as the technological system that human beings are increasingly dependent on. [0003] At present, human beings mainly rely on radio waves for satellite-ground-space communication, and the frequency ranges from a few MHz to tens of GHz. Global satellite navigation and positioning systems (GPS, GLONASS, Beidou, etc.), which are widely used in the world, provide positioning and timing services for ground equipment through multiple satellite...

AI Technical Summary

Problems solved by technology

[0010] At present, there are no solar radio interference equipment and instruments specifically for the Beidou system in China. The radio interference alarm service mainly uses relevant foreign data, which is poor in real-time, regional and effective, and cannot meet the needs of scientific research and application services.
