Start with Range extender

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 controller antennas in a better location, closer to the drone, it is possible to extend the range of the drone. The Range Extender is an optional accessory that connects to Elios 3 ground control station, providing an extended signal reach for beyond line-of-sight operation.

This video will explain all the good practices and limitation of the Range extender.
