The drone is tethered to the base unit with a flexible cable which feeds power to the drone allowing it to remain in flight for up to 48 hours continuously. The cable also provides for communication and data exchange between the two.
The system has “hot drop” capability, and the power/communication cable can be dropped whilst in flight and at altitude, after which Sky Mantis can fly for another 30 minutes. This is useful if there is an immediate requirement for a moving vehicle to be tracked, for example.
Tethered drone surveillance is useful in situations where there is only a limited operating area to be overseen, and flight endurance is required for persistent surveillance. Typical applications include ‘Blue light’ organisations (particularly the Police), Military and Security services (for intelligence and reconnaissance), disaster response, event management, and at shipping ports to monitor people and cargo movements. Data transmitted through the drone tether is more secure than wireless signals as it is less susceptible to interference.
