ISR operations give live and encrypted feedback to the operator showcasing all objects of interest like hostiles, friends, vehicles, weapons, structures etc at the target location.
There are variations of tethered drones, ranging from a standard drone tethered to ground power using regular fishing line, to programmed, tension sensing, auto reeling specialized hardware tether that employ a high voltage, direct current to operate the drone.
The tether cable contains high tensile strength, lightweight and thin conductors, which reduce the wind drag, enabling the drone to reach a higher altitude (around 300- 400 feet).
A Power station (aka drone station or tether station) on the ground converts AC electricity into the higher-powered DC. The drone itself also has a DC-DC converter to supply lower-voltage power to the payload system and other onboard components.
Specifics of operations will vary per company as they have different designs for their tethered drone systems. Tethered drones are also easy to deploy and retract using a winch system, with varying levels of sophistication, to which they are typically connected.
