System for early warning of interference of solar radio burst on satellite communication based on air-ground joint observation

Abstract

The invention discloses a system for early warning of interference of solar radio burst on satellite communication based on air-ground joint observation. The system comprises a high-energy ray detector system carried on an on-orbit satellite platform, a ground-based solar radio telescope and a computer, wherein the high-energy ray detector system carried on the on-orbit satellite platform comprises a high-energy ray detector, a signal processor and a transceiver I; the high-energy ray detector is connected to the transceiver I through the signal processor; and the transceiver I is connected to the computer through the ground-based solar radio telescope. The system arranges threshold information mutual communication mechanisms to the high-energy ray detector system carried on the on-orbit satellite platform and the ground-based solar radio telescope for the physical nature that the X ray burst and the radio burst are asynchronous, when the observation flow of one frequency band exceeds a threshold, information is sent to an observation system of the other frequency band and the related preparations are made; the device can obtain more accurate and reliable early earning information, the early warning aging is prolonged and the early warning effect is improved.

Description

technical field [0001] The invention belongs to the field of satellite operation monitoring, and in particular relates to an early warning and forecast system for events in which solar radio bursts interfere with satellite signals. 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 satellites, and play a huge role in military, scientific research, offshore oil and gas field drilling and other fields.
