METHOD OF DETERMINING AURORAL OVAL POSITION AND STATE OF THE EARTH'S MAGNETIC FIELD Russian patent published in 2016 - IPC G01V3/00 

FIELD: geophysics.

SUBSTANCE: invention relates to geophysics, and it can be used in environmental monitoring system, monitoring of near-Earth space environment. Proposed method is implemented by arrangement of the receiver or several receivers in zones of polar caps and auroral ovals, by calculation of values distribution of full electronic content in the atmosphere (FEC) along the trajectories of the podiosphere points of spacecrafts (SC) in the visibility range of each receiving device, allocating SC podiosphere points trajectory nearby magnetic meridian of the receiving devices. From the position of FEC extreme values on FEC calculated maps or from the position of FEC extreme values along trajectories of SC podiosphere points nearby magnetic meridian of the receiving devices selecting the auroral oval Equatorial boundary. FEC is calculated by delays of received signals at SC working frequencies with gaging by the climatic models of the ionosphere and calculated hardware, instrumental and tropospheric errors. In order to specify the auroral oval position calculated vertical profiles of the concentration of charged particles along the SC trajectories are used, available sources of information, including maps of FEC distribution over the receivers network of GNSS signals in near-auroral zones, radars and other observation means, as well as data archives of the ionosphere probing, adaptive models of high-latitude ionosphere and auroral oval.

EFFECT: technical result - increase of efficiency, accuracy and reliability of auroral oval monitoring zone and the state of the Earth's magnetic field on the calculated characteristics of high-latitude ionosphere on the basis of reception time-synchronized and encoded SC signals, including global navigation satellite systems and geostationary SCs, taking into account weather data about auroral oval position.
