South Korea's Uconsystem, a subsidiary of Foosung Group, has updated its RemoEye 002B short-range mini unmanned aerial vehicle (UAV) with a vertical take-off and landing (VTOL) capability.

The new variant is identified as the Remo-TOL and is equipped with lift/descent assemblies under each wing - carrying electric motors located fore and aft in fixed mounts - that provide vertical lift before transitioning to conventional flight.

As with the baseline RemoEye-002B, the Remo-TOL's composite airframe measures 1.44 m long and comprises a fuselage pod that supports a nose-mounted sensor turret, a high-mounted 1.8 m wing with a rear-mounted electric motor outfitted with a pusher propeller, and a tailboom that terminates in a conventional horizontal and vertical surface tail assembly.

However, the Remo-TOL has a higher maximum take-off weight (MTOW) of 4 kg as opposed to the RemoEye-002B's 3.4 kg rating, resulting in a reduced endurance of 50 minutes - 10 minutes less than the latter air vehicle. Uconsystem is also quoting a comparable maximum level flight speed of 80 km/h and operational range of 10 km.

It can be similarly equipped with a stabilised electro-optical/infrared payload that features 2-axis pan and tilt scanning.

A Foosung Group representative told Jane' s that the Remo-TOL leverages on the reliability and proven performance of the RemoEye-002B, which is in service with the Republic of Korea Army (RoKA) and has already accumulated more than 10,000 hours of field operations since the air vehicles were introduced in 2015.

"We developed the Remo-TOL based on user feedback in 2017 and began marketing the system earlier this year," the representative said. "We are planning to demonstrate it to the army in 2019."

Jane's previously reported that the company has supplied about 120 RemoEye-002B systems - each system comprising four air vehicles - to the RoKA for battalion-level close-range intelligence, surveillance, target acquisition, and reconnaissance (ISTAR) missions under a contract awarded in late 2013.
