Problems solved by technology

[0006] 2. Low temporal resolution
[0008] 3. Unable to monitor in real time
Furthermore, initial electron density values ​​are usually only available ex post and the time resolution of the tomography is very low
These limitations have made real-time 3D ionospheric electron density monitoring using 3D ionospheric tomography techniques unavailable.

Abstract

The invention discloses a CORS-based regional ionospheric electron density three-dimensional real-time monitoring system and method. The real-time monitoring system comprises a CORS data real-time acquisition module, a Real-Time Service (RTS) real-time acquisition module, a real-time precise ephemeris generation module, a real-time data management module, an ionospheric data processing module, a display module and a product service module. The CORS-based regional ionospheric electron density three-dimensional real-time monitoring system and method has the significant effects that real-time three-dimensional ionospheric electron density products based on global satellite navigation systems such as GPS, GLONASS or Beidou system can be stably provided in real time through a GNSS reference station network and the ionospheric data processing module, and real-time monitoring of a regional ionosphere is realized; and the realization cost is low, ionospheric products with real-time and high spatial-temporal resolution are provided without increasing the construction cost, and the CORS-based regional ionospheric electron density three-dimensional real-time monitoring system and method is apowerful supplement to traditional ionospheric monitoring methods.

Description

technical field [0001] The invention relates to the technical field of ionospheric real-time monitoring, in particular to a CORS-based three-dimensional real-time monitoring system for regional ionospheric electron density. Background technique [0002] The traditional methods for detecting the ionosphere include ionospheric altimeter and incoherent scatter radar and other technologies. The ionospheric altimeter, as the main equipment for vertical observation of the ionosphere on the ground, has always provided important measurement data for the observation and research of the ionosphere. However, the altimeter has the disadvantages of being expensive, can only detect the electron density in the vertical direction, and cannot detect the electron density above the F layer; the price of the incoherent scattering radar is much higher than that of the altimeter. The emergence of GNSS provides a new technical means for ionospheric monitoring. [0003] Using GNSS for three-dimen...
