Recently I lost a unit of my FX61 UAV workhorse during mission in peat swamp forest in Sarawak interior. I have this unit in service for the last 3 years.
It was my mistake, I overestimated the remaining battery reserve was enough to complete the last survey line before RTL. It was sudden very strong wind during that last line and there was no telemetry connection due to trees obstruction.
Few years ago I heard about GPS pin point device used by conservationist to locate birds and the device transmit X,Y locations through radio frequency. I dont know if anyone has tried use it for UAV.
Now I was thinking if you guys know any device, ways or tools can be use to locate lost UAV units?
