Peer-to-Peer Cooperative Positioning

Working Papers explore the technical and scientific themes that underpin GNSS programs and applications. This regular column is coordinated by Prof. Dr.-Ing. Günter Hein, head of Europe’s Galileo Operations and Evolution.

In peer-to-peer (P2P) networks, communication nodes can communicate with their neighbors without central coordination. By exchanging data, the network can perform cooperative positioning: each node is helped by its neighbors to compute its position.

SIDEBAR: Safe Navigation from Hybrid, Redundant Navigation Sensor Sys¬tems

Return to main article: "Drones to the Rescue!"

Navigating safely is always necessary, and unmanned platforms especially need to do so, as they still must demonstrate to the general and technical public that flying without a pilot on board works and is safe (or as safe as piloted crafts). So, when asking ourselves what is the right approach to safe navigation in UAVs, one word steps immediately into the discussion: redundancy.
