In environments such as underground galleries, stacks or mines, signal propagation can be limited by the geometry of the place to inspect and remotely operating a robot becomes difficult. By placing the remote control antennas to a better location, closer to the drone, it is possible to extend the range of the drone.

To that end, Flyability has developed the Range Extender: an accessory that connects to Elios ground station, providing an extended signal reach for beyond line-of-sight operation.

From underground mining, sewer inspections, enclosed spaces inspection and even search and rescue, the Elios Range Extender has a range of applications.
