Team West Coast UAV achieved one of our major milestones during testing on the weekend, controlling multiple UAVs through a multi-point comms network suitable for the 2016 Outback Challenge.
One of the main challenges for our mission will be establishing reliable communications between our ground station and the retrieval aircraft when it lands at a distance of over 10 km away. To solve this we will keep our support aircraft flying in the air and use this to relay the telemetry from the ground station to the retrieval aircraft on the ground.
On the weekend we successfully demonstrated the relay concept in the field using a 1W 900 Mhz radio link between the ground station and the support aircraft (Ben’s X-UAV Talon), and then relayed to the second telemetry link to the retrieval aircraft (Steve’s Crash Test Hobby Reaper) using a 25mW 433 Mhz radio link. Both aircraft were fully controllable in autonomous flight. The retrieval aircraft was flown to a distance of 700m from the support aircraft and still maintained a reliable link.
