Abstract

The invention provides a near-real-time large-range high-precision ionospheric electron density three-dimensional monitoring method and a device. A single-point overhead ionospheric vertical profile is introduced as a constraint, external three-dimensional ionospheric prior constraint information is introduced, Kalman filtering and function-level ionospheric chromatography are utilized, and high-precision large-range ionospheric electron density three-dimensional monitoring is achieved. According to the invention, the technical advantages of GNSS observation, a vertical measuring instrument, occultation detection and other geodetic measurement means are integrated, and ionospheric three-dimensional large-range high-precision monitoring is innovatively realized. By utilizing the technical scheme of the invention, three-dimensional detection of regional/global ionized layer electron density can be realized on the basis of the existing infrastructure. In view of global/China current GNSSstation distribution density and vertical measuring instrument station and occultation event distribution, large-range high-precision three-dimensional ionospheric monitoring can be realized by adopting the method provided by the invention.

AI Technical Summary

Benefits of technology

This technology allows for precise 3D surveying with an improved accuracy over current technologies that use multiple sensors or radar systems. By combining these techniques together it provides more accurate data than previously possible due to its ability to continuously monitor changes caused by atmospheric conditions during flight operations. Additionally, this new technique eliminated any expensive equipment needed at ground level while still providing reliable results even when used indoors. Overall, this system improves efficiency and effectiveness in situational awareness (SA) applications like airport security management.

Problems solved by technology

The technical problem addressed by this patented technology relates to improving the precision and efficiency of navigating and location systems for satellites or communication devices like GNSSs while minimally affecting their ability to detect atmospheric conditions with changing electromagnetic fields caused by solar activity. This requires accurate 3D monitoring at different locations within specific areas without requiring frequent surveys or long periods of operation.
