Blue Vigil is the U.S. industry leader in tether power systems for drones. The company has designed a reactive spool tether system that connects to most off-the-shelf drones. The tether system is self-contained, includes proprietary power management circuitry and a flight control system. Drones powered by the RS1000 ground-based tether system can remain aloft as long as power is conveyed through the tether, and they do not require a dedicated operator. Blue Vigil was founded and is managed by a team of pilots and UAV experts. The team saw an unfilled need in the UAV industry for a tether system that was universally compatible with UAVs. Blue Vigil was founded in 2015 in partnership with a Harrisonburg, Virginia Investor Group, and James Madison University.
