Abstract
An inertial navigation device error correction system includes an inertial navigation device, a coordinate calculation device, and an error correction device mounted on each of aerial vehicles. The coordinate calculation device calculates coordinates of a second aerial vehicle with respect to a first aerial vehicle. The error correction device calculates azimuth and elevation angles of the second aerial vehicle based on first data on the first aerial vehicle, and azimuth and elevation angles of the second aerial vehicle based on second data on the second aerial vehicle. The error correction device corrects an error caused in the inertial navigation device of the first aerial vehicle, on the basis of angle measurement residuals that are differences between the azimuth and elevation angles of the second aerial vehicle based on the first data and the azimuth and elevation angles of the second aerial vehicle based on the second data.
