The PD-100 Black Hornet (micro world)

The PD-100 Black Hornet is under Norwegian Arms Control and will only be sold to government institutions and organizations.
The Black Hornet is constructed of a rugged, plastic-moulded shell. The aerodynamic shape of the nano UAV withstands stormy winds. The tiny drone is fitted with three surveillance cameras concealed within its nose. The complete PD-100 Black Hornet system includes two UAVs and a base station.
The UAV has a length of about 100mm and rotor span of 120mm. It has a weight of 16gm including that of the surveillance camera. The total system excluding display weighs less than 1kg.

The ultra-compact dimensions of Black Hornet enable the operator to use it in congested and threat-prone areas effectively. The system generates almost negligible noise, making the aircraft more stealthy and re-usable. The small UAV is readily available to fly and takes less than a minute for takeoff.
The Black Hornet is installed with a steerable electro-optic (EO) camera capable of producing still images as well as live videos that are displayed on a hand-held device. The camera can be zoomed for clearer picture using the base station controls.

The Black Hornet micro UAV is powered by a very small rechargeable battery. The battery is designed to rotate both horizontal and vertical rotors installed on the drone.
