Unmanned erial vehicle INDELA-I.N.SKY

uav helicopter Indela I.N.SKY


The unmanned aerial vehicles INDELA-I.N.SKY of a medium operating radius is designed to fulfill a wide range of practical tasks:

- twenty-four-hour monitoring of specified territories, water surfaces, industrial projects, vehicles, boats, yachts, ships, groups of people, individuals etc.;

- real-time video and infra-red information transmission to the ground control station at a distance of up to 50 km within line of sight from a ground control station during 5 hours;

uav helicopter Indela I.N.SKY

The construction of INDELA-I.N.SKY UAV, at the customer's option, allows installing additional equipment into the payload compartment, which expands range of application of the complex for other tasks. The UAV construction allows building up flight and navigation equipment and installation of different variations of payload. Ground control station (GCS) includes all the necessary components for flight programmed control and real time equipment diagnostics. The helicopter is based on a classic single-rotor scheme with a tail rotor.

«I.N.SKY» use gyro-stabilized optoelectronic system «INDELA OG-20».

Biaxial gyro-stabilized suspension «INDELA OG-20» ensures high level of stabilization due to the up-to-date gyroscopes of the leading manufacturers and modern software.Three-dimensional inertial system is based directly on an optic installation.Neural net, data and knowledge base, high-performance computer and high-class software all together form an object recognition system. This system recognizes and constantly carries out videotracking of the objects, selected by the operator. Adjustable OSD supplies a wide range of parameter settings and additional symbols. Adjustable parameters: composition, isposition, transparency, colour.
