Eleron–3 remote observation system


Purpose of the system

The system is designed for round-the-clock airborne optoelectronic reconnaissance and provides:


Visual search of reconnaissance objects by the operator in real time;

Detection and identification of reconnaissance objects;

Pinpointing the exact location of these objects with coordinates displayed on the ground control panel via GLONASS / GPS;

Aerial photography of the area.

Recommended applications

The system is designed for round-the-clock airborne optoelectronic reconnaissance and provides:


Monitoring the ground situation, protecting territories and objects from the air

Border patrols, coast guard patrols, and control of territorial waters

Search-and-rescue support

Monitoring the condition of highways and railways

Monitoring the condition of oil and gas pipelines and power lines

Environmental monitoring of land and water areas, and air basin

Mapping and aerial photography

Fishery exploration and control of fishing

Aerial reconnaissance and electronic warfare

Monitoring GSM communication networks, determining the required parameters and coordinates of mobile communication devices with positioning on an electronic map

Ice situation monitoring

Monitoring the ground situation during forest fires

Monitoring settlements cut off by floods

Monitoring the state of engineering structures during ice drift.

* Flight modes:


Autonomous — by uploading the task programme into the onboard memory before launch, the flight can be performed in the radio silence mode of the onboard data transmission facilities and the absence of UAV control from the GCS.

Automatic — the task programme is uploaded into the onboard memory before launch; it can be adjusted mid-flight from the GCS.

Semi-automatic — the UAV flight direction and/or height is controlled by commands from the GCS.

The system is delivered ready for operation after undergoing mandatory flight tests.
