Though the idea of an eVTOL vehicle for the forward edge of the battlefield is not new, the revolution in low-power computer processing, high-efficiency electric motors, and composite materials has helped turn this idea into reality.

SURVICE partners with leading-edge companies around the world to develop and deliver innovative, disruptive new technologies. Our work in unmanned aircraft systems development and testing is an example of providing new game-changing capabilities to the Warfighter for transportation and logistics. The TRV family of drones, developed in collaboration with UK-based Malloy Aeronautics, represents field-proven capability at tactically significant payloads and ranges.

SURVICE Robotics and UAV Research Facility

ATO’s new 15,000 ft2 drone facility supports development and testing of the latest in unmanned multirotor platforms and integration of custom payloads and autonomous technologies. It supports advanced prototyping capabilities, including custom electronics, high-performance computing, and the latest in virtual reality and augmented reality visualization. While specifically targeting tactical applications supporting the DoD, many of the developed and integrated technologies range from military to commercial applications. 

The facility is FAA COA certified for Group 3 VTOL flights (120 acres at an altitude of 400 ft). Because it is co-located at the Harford County Airport, SURVICE has access to dedicated flight space for operating our drones, enabling us to conduct flight testing in a secure and safe space.
