During light day with PS-11 you can obtain photo images of territories, satellite photo images, remote air surveillance of objects (separate buildings, roads, bridges, vehicles, oil/gas pipelines, electric power transmission lines etc.). Conducting imagery intelligence of ground situation during emergencies (fires, earthquakes, floods, man-made accidents) and search and rescue operation. Obtained telemetry and video (photo, infrared) data can be transmitted online or be recorded on onboard recorder.

Pseudo Satellite PS – 11 “KROKUS” is a two engine aircraft – high wing with pull airscrews, which are located on wing pylons. Airframe is made of fiber glass/carbon fiber, separate loaded elements of construction are made of high strength aluminum alloys. Tail unit covering is made with lavsan coat. Wing covering is combined.

Main advantage of PS-11 is board power supply, which consists of more than 300 solar cells. Solar cells provide energy for aircraft systems, its power plant and payload. World analogs of this UAV: Zefir -7/8 (Great Britain), Pathfinder (USA) and others.
