Rapid pre-warning system for event that navigation communication is interfered by solar radio burst

Abstract

The invention discloses a rapid pre-warning system for an event that navigation communication is interfered by solar radio burst. The system comprises a transmitting device integrated with a monitoring satellite, and a receiving device and a signal gain adjustment device integrated with a navigation communication satellite. The signal gain adjustment device is integrated with the navigation communication satellite. The transmitting device integrated with the monitoring satellite is composed of a plurality of X-ray detectors with amplifier circuits, a signal processing system, a signal transmitter and a transmitting antenna which are connected in sequence. The receiving device integrated with the navigation communication satellite is composed of a receiving antenna and a signal receiver which are connected. The transmitting antenna is connected with the receiving antenna. The signal receiver is connected with the signal gain adjustment device. According to the system, in a solar high energy observation plus inter-satellite rapid pre-warning mode, pre-warning information can be accurately and rapidly transmitted to satellites such as navigation and communication satellites which arepossibly influenced, and the condition that a signal carrier-to-noise ratio is influenced can be effectively improved.

Description

technical field [0001] The invention belongs to the field of satellite operation monitoring, and specifically relates to a rapid early warning technology for solar radio burst interference navigation communication events based on space high-energy observation and intersatellite communication technology, which is suitable for early warning and forecasting of solar radio burst interference satellite signal events. 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 positionin...

[0007] Image 6 It is obvious that during the radio storm, my country's Kunming, Taiwan, Wuhan, Beijing and other GPS stations were obviously out of lock, and the signals of multiple stations and GPS satellites were completely interrupted for up to 6 minutes. , the number of satellites locked by multiple stations is less than 4, making the GPS real-time positioning service completely invalid;
