Problems solved by technology

The above methods all have to rely on special-purpose satellites, and the monitoring time is long, which makes it difficult to meet the complete coverage of the monitoring area, let alone the global coverage monitoring capability, and it is difficult to meet the needs of quickly obtaining global atmospheric and ionospheric information during wartime (The data within 2 to 3 hours is required in wartime), which cannot meet the needs of providing real-time binding of relevant atmospheric parameters for precision strike weapons

Abstract

The invention relates to a space-borne ionospheric amplitude scintillation monitoring device. The device adopts a dual-frequency GPS satellite navigation receiver mounted on a low-orbit satellite, and uses the GPS receiver to perform satellite precise orbit determination and ionospheric scintillation monitoring. The navigation signal received by the satellite navigation receiver is processed to obtain the ionospheric amplitude scintillation detection parameters, obtain the ionospheric distribution, and improve the ionospheric scintillation and disturbance detection level. The device can make full use of GPS satellite navigation signals with global coverage and continuous Uninterrupted characteristics, improve the ability of atmospheric ionospheric monitoring data processing, the device can also take advantage of the fast flight speed of low-orbit satellites, achieve the purpose of short global ionospheric detection time, and improve the real-time performance of atmospheric ionospheric amplitude scintillation monitoring and global coverage.

Description

technical field [0001] The invention belongs to the technical field of satellite navigation and space weather forecasting, and in particular relates to a spaceborne ionospheric amplitude scintillation monitoring device. Background technique [0002] The ionosphere is a part of the atmosphere sixty kilometers to several thousand kilometers away from the earth's surface. Due to the influence of solar electromagnetic radiation and high-energy particles, this part of the atmosphere is ionized to form a plasma state. This layer of atmosphere will refract radio signals propagating through it. , Scattering, absorption, scintillation and Faraday rotation and other effects will change the speed, direction, phase, amplitude and polarization state of the propagating signal, and, due to the inhomogeneity and random time-varying nature of the ionospheric structure, it will also cause the propagating signal Short-period irregular changes in the amplitude, phase, angle of arrival, polariza...
