Title:
DRONE COOPERATIVE NAVIGATION USING GNSS ERROR SHARING
Document Type and Number:
WIPO Patent Application WO/2024/096387
Kind Code:
A1
Abstract:
The present invention relates to cooperative navigation of multiple drones using GNSS error sharing and a method for operating a navigation device. The cooperative navigation of multiple drones including a first drone and a second drone may comprise the steps of: setting a first initial absolute location value of the first drone on the basis of GNSS measurement values; acquiring a first absolute location estimation value on the basis of the first initial absolute location value and a first sensor measurement value acquired via a sensor unit included in the first drone; calculating a GNSS error between the first initial absolute location value and the first absolute location estimation value; transferring the calculated GNSS error to the second drone; and calculating a relative location, based on an industrial structure, of the second drone on the basis of the transferred GNSS error.
