METHOD AND NETWORK CENTRIC SYSTEM FOR DETERMINING IONOSPHERIC PARAMETERS Russian patent published in 2024 - IPC G01W1/08 G05D1/10 G08G5/02 

FIELD: geophysics; meteorology.

SUBSTANCE: invention can be used in navigation and communications. The essence of the method for determining the parameters of the ionosphere is to use a group of unmanned aerial vehicles (UAVs) as a carrier of sounding equipment. When implementing the method, the following is carried out: preparing a group of copter-type UAVs with sensing equipment placed on them, selecting an ionospheric sensing area with indication of coordinates, preparing UAV flight tasks, launching a group of UAVs to perform a flight mission, landing a group of UAVs and joint processing of measurement data. The network-centric system that implements this method consists of control points and groups of copter-type UAVs with sensing equipment placed on them, including emitting and receiving antennas, units for generating and receiving chirp radio signals, a synchronization unit with a built-in GPS-GLONASS receiver that ensures synchronization of chirp radio signal radiation from one UAV and reception of signals reflected from the ionosphere on other UAVs of the group, a memory unit and a radio channel unit that provides input of a flight mission.

EFFECT: increasing the efficiency and expanding the range of determination of the state of the ionosphere, increasing the reliability of HF communications, and increasing the accuracy of navigation equipment.
