Abstract

According to one implementation, an aviation systemincludes electric field sensorsand a ground systemincluding a computer configured to communicate with each of the electric field sensors. The computer is configured to: acquire electric field intensities from the electric field sensorsrespectively, and generate a first electric field distribution on a ground surfacebased on the electric field intensities; derive a matrix; derive a pseudo inverse matrix of the matrix; derive an electric charge distribution on the horizontal plane by multiplying the pseudo inverse matrix by the first electric field distribution on the ground surface; and derive a second electric field distribution on a flight path based on the electric charge distribution. The first electric field distribution on the ground surfaceis derived by multiplying the matrix by electric charges temporarily set on a horizontal plane at a predetermined altitude.
