Have you ever lost your quadcopter? I’ve done this myself a few times, but since it was a little Hubsan X4, it never wandered too far before loosing signal and crashing. If, however, you have a larger quadcopter capable of traveling much, much further, then perhaps a tracker like this one could come in handy. The device (or pair of devices) consists of a unit that is attached to your quadcopter and transmits its GPS coordinates to a receiver that you keep on your person. Combined with another GPS unit (e.g. a smartphone), this should allow you to track down errant “drones.”
One advantage of this over other GPS tracking units on the market is that this one doesn’t use a cell signal. This means you don’t have to pay for cellular service, and it can be used in places where this type of service is spotty or nonexistent. On the other hand, the range is limited to about a kilometer in line-of-sight conditions, so you might not want to have it stray too far!
Besides quadcopters, I’m certain there are other interesting uses for this type of device. Maybe we will see an innovative use of this pair sometime soon!
