The ECARYS ES15 unmanned aerial vehicle from Stemme will be converted into an Optionally Piloted Vehicle (OPV) using S-PLANE subsystems.

A comprehensive solution will be created, including a Ground Control Station, suitable for a variety of mission profiles. The OPV is a highly versatile vehicle, combining the benefits of a manned aircraft with those of a UAV.

As a manned aircraft, the OPV can execute missions that demand human judgement and control, such as flight in civil airspace, over congested areas, flying at low level and transporting passengers.

When the pilot is removed from the cockpit the system can perform unmanned missions that require extreme endurance or are more dangerous to perform. These include critical infrastructure protection and surveillance, border and maritime patrol, cargo delivery, firefighting and HAZMAT containment.

The ECARYS ES15 is a proven, certified high performance aircraft platform with a 770 lb (350 kg) payload capacity and a 1.350 nm (2.500 km) range. It is characterised by low fuel consumption, low noise emission and low maintenance requirements.

Stemme says its low radar and minimal IR signature make it an ideal platform for surveillance missions. The aircraft can operate in mission-driven mode where the entire flight from automated take-off to automated landing is directed by the on-board control systems.

Alternate landing sites, escape routes and emergency handling procedures are defined in the mission profile to ensure safe operation under varying conditions.

A remote pilot can take control of the aircraft at any time, altering the mission or interactively controlling the aircraft and payload. High bandwidth Line-Of-Sight links provide real-time payload video at the Ground Control Station while Beyond-Line-Of-Sight operation is enabled via satellite links.
