The Sitaria fixed-wing unmanned aircraft system (UAS) from UAVOS recently completed a series of test flights. The new system is designed for patrol and observation missions and aerial photography of terrain with a radius of up to 120 kilometers, as well as to work with LiDAR airborne laser scanning equipment.
The system can achieve a wide range of speeds, according to a news release.
“During monitoring missions, a wide range of speeds allows Sitaria fixed-wing drone to quickly reach the object and return back at the optimal speed,” said Vadim Tarasov, UAVOS investor and board member. “Takeoff and landing is carried out at low speeds, which makes it possible to use short runways. All these features directly affect safety, and also optimize operating costs.”
The UAS weighs 35 kilograms and has a wingspan of 5.2 meters. With a payload of 4 kilograms, flight time is three hours. Video transmission range can reach up to 60 kilometers. The backup Iridium command line has unlimited range. The EW countermeasure function provides an opportunity to carry out research under jamming of satellite radio navigation signals and the command line channel.
The system features an electric motor, which is described as less noisy and more reliable. Its aerodynamic design makes it possible for the UAS to quickly adjust wing position relative to the fuselage when the payload weight changes. The minimum tail weight has a positive effect on the system’s control and stability.
“Technical solutions, implemented in Sitaria, provide the high level of fail-safety, reliability and security that is required for operation in diverse areas of commercial applications of the UAV,” Tarasov said.
