The idea behind the project is to provide a extended search radius to search and rescue (SAR) missions on the sea:
Without intelligence from the air, the search radius on a ship, using binoculars to search the sea, is limited to a range of approx. 3 nautical miles (5 km) due to waves and the curvature of the earth.
Our drone, flying at approx. 300-500 m above the sea, equipped with a 8 mega-pixel camera and a computer, extends that range and can cover an area up to 30 square-kilometres per mission.
To get more details on the technical specifications you can check the preliminary datasheet:
MiniTalon - the plane
The Pixracer is already equipped with most of the needed sensors for our autonomous missions.
The extra precision needed for both the missions and also for the landing in the net is provided by the special drone GPS module.
Telemetry for extended range
For the communication with the plane during the mission a telemetry link with extended range is needed: the Australian company rfDesign offers excellent modules for this.
We could measure distances over 80km.
Over this link the drone can not only receive missions but als return the position of possible people in distress - including pictures.
Camera and image processing
The pictures taken by the attached 8 MP camera are stored on the Raspberry for later manual or automatic evaluation.
