AI Technical Summary

Technical Problem

The location information in remote IDs transmitted by unmanned aerial vehicles (UAVs) contains errors due to varying reception status of GNSS signals, leading to inaccuracies in flight position calculations, which complicates operation management, especially in limited airspace.

Method used

A position calculation device that uses a standard movement pattern to select a plausible determined position from multiple position readings, correcting for environmental factors and deviations, and determines the actual flight position of the UAV.

Benefits of technology

Improves the accuracy of calculating the position of UAVs by mitigating errors in GNSS-based location information, enabling effective operation management and trajectory tracking.

Abstract

A position calculation device according to the present invention is provided with an acquisition unit and a confirmation unit in order to improve the calculation precision of a position of an autonomous vehicle calculated using position information transmitted by the autonomous vehicle. The acquisition unit acquires identification information transmitted at a predetermined transmission timing by the autonomous vehicle. The identification information includes unique vehicle body information given to the autonomous vehicle, position information representing the position of the autonomous vehicle, and time information. The confirmation unit uses a predetermined standard movement pattern to select the most likely measured position as the position of the autonomous vehicle from among measured positions, which are the positions of the autonomous vehicle represented by the position information included in each of the plurality of pieces of identification information that have been acquired. The confirmation unit confirms the selected measured position as the position of the autonomous vehicle.
