Zenith Aerotech keeps tethered aerial vehicle aloft for 108 hours of continuous flight


AFTON, VA: Zenith Aerotech, a leading developer of heavy-lift tethered aerial vehicles (TAVs), announced that, over the span of a week, its Quad 8 multi-rotor platform flew a total of 161 hours and 49 minutes—108 hours of which were continuous, uninterrupted flight.

In doing so, the TAV far exceeded the capabilities of competing tethered drones and demonstrated its ability to serve as a long-endurance platform for persistent surveillance.

“Small, multirotor-type drones are notorious for their limited air endurance. By contrast, tethered aerial vehicles, which draw power from a generator on the ground, can stay aloft for hours at a stretch,” said Kutlay Kaya, CEO of Zenith Aerotech. “But no other TAV company has ever been able to fly a platform for as long as we just did. This is a major technological breakthrough for small unmanned systems.”

The test, which took place over a seven-day period at the company’s facility in Afton, was initiated at the request of a government customer prior to delivery. The Quad 8 TAV, which carried an electro-optical/infrared camera and an Echodyne EchoFlight radar, flew for most of that time, only coming down twice, during lightning storms, which had to be waited out.

“We observed all the FAA regulations for day and nighttime operation,” Kaya said. “Our team was on site around the clock, with people taking 8-hour shifts to watch the TAV and the Ground Power-Tether Management System. There were two times we had to bring down the Quad 8, but as soon as those storms subsided, the TAV was back in the air. We flew through 18 hours of light to heavy rain with wind gusts up to 40 mph.”

Zenith Aerotech recently partnered with Sydney-based DroneShield to provide enhanced drone-detection capabilities and countermeasures. In putting DroneShield’s DroneSentry-C2 command-and-control application, along with an Echodyne radar, onto a TAV, Zenith AeroTech provided a platform with a higher elevation than the standard mast. This eliminated clutter and false positives, allowing for better counter-drone detection. Now it provides extreme long-endurance too.

“By demonstrating more than 100 hours of flight time, we’ve opened up our TAV to all sorts of mission sets and customers,” Kaya said. “It’s a really very exciting.”

Zenith Aerotech to offer DroneShield counter-drone capabilities on tethered aerial vehicles


AFTON, VA: Zenith Aerotech, a leading developer of highly customizable, heavy-lift tethered aerial vehicles (TAVs), announced today that it is partnering with Sydney and Virginia-based DroneShield to provide enhanced drone detection capabilities, along with a range of countermeasures.

As part of the distribution agreement with DroneShield, Zenith Aerotech will incorporate DroneShield’s DroneSentry-C2TM command-and-control ecosystem into its own family of TAVs, along with an Echodyne EchoFlight radar, to counter drone or drone swarm attacks.

“By putting a detection capability on a TAV, which typically flies at 400 feet, you get better range than if you were to have these systems on a pole or ground vehicle,” said Kutlay Kaya, CEO of Zenith Aerotech. “Also, your alerts will be more accurate because, at elevation, you’ve eliminated clutter.”

The integration of Echodyne radars on Zenith Aerotech’s TAV also enables simplified mission planning, added Shane Shamblin, Echodyne’s director of DoD Programs. Zenith AeroTech offers three different TAV platforms: Hexa, Quad 8, and Quadro.

In contrast to standard drones, these three TAVs can stay aloft for hours—and even days—at a stretch thanks to Zenith’s Ground Power-Tether Management System, which converts 120- or 240-volt AC power from a generator (or another source) into high-voltage DC, powering both platform and payload.

The platforms themselves can carry 10-30 pounds of payload, and Zenith AeroTech is always experimenting with different mixes of sensors, communications and other equipment to proactively address emerging threats.

In addition to a capable drone-detection solution, the company will be offering DroneShield’s and soft kill measures, to be used by personnel on the ground. “Because we detect inbound drones from further away, we give personnel on the ground more time to jam them,” Kaya said.

There are many potential markets for TAVs with counter-drone capabilities. The military could use them to protect forward operating bases; civilian security managers might have them fly over sensitive facilities; and law enforcement could use them to safeguard well-attended public events.

“We are already working with a couple of federal agencies, and we anticipate broader adoption of this solution,” Kaya said.

DroneShield’s CEO Oleg Vornik has commented, “DroneShield’s deployment with Zenith takes our cutting edge command-and-control ecosystem capabilities into the tethered drone domain, opening a new range of applications for our Government end-users.”

Zenith Aerotech mounts radar, networking radio, and EO/IR camera on small, tethered drone


AFTON, VA: Zenith Aerotech announced today that it has integrated an advanced flight radar, gimbaled EO/IR camera, and mobile ad hoc networking radio on the company’s Quad 8 tethered mid-range, unmanned aircraft system (sUAS).  The engineering work, which was done at the behest of an unnamed Federal customer, demonstrates how the long-endurance, tethered sUAS can support force protection and early warning missions.

Able to fly at 400 feet AGL for hours—and even days—at a time, the tethered Quad 8 draws power from an easily transportable ground power unit. Zenith Aerotech’s sUAS line, can carry a variety of payloads, from 10 to 24 lbs. Until now, the company has never flown this combination of advanced sensor and communications equipment on the Quad 8.

“We are very excited to have worked with so many cutting-edge industry partners on this effort,” said Kutlay Kaya, CEO of Zenith Aerotech. “With their collaboration, we were able to have our Quad 8 carry Echodyne’s Advanced EchoFlight radar, Trillium Engineering’s HD45 gimbaled EO/IR camera, and the Persistent Systems MPU5 mobile ad hoc networking radio.”

The next step for the company is to demonstrate the capability of the platform with all these integrated payloads, said Mr. Kaya.

“We plan to show how we can simultaneously collect high-resolution imagery, both electro-optical and thermal, as well as air- and ground-based radar anomalies and then securely deliver these collections through the MPU5, providing a robust overwatch capability,” Kaya said. “The MPU5 also acts as a radio/data relay to support disaster recovery operations and provide secure communications.”

The planned platform/payload demonstration shows the versatility of Zenith Aerotech in meeting customer’s needs, whatever they may be. “Whether our customer is a first responder agency, media company, or armed service, we strive to develop and deliver relevant capabilities in a timely fashion,” Kaya said.


Zenith Aerotech Exhibits At 2020 National Public Safety UAS Conference

This year’s event was held at King Family Vineyards in Crozet, Virginia, and hosted around 200 law enforcement, public safety, search and rescue, emergency services, and disaster relief professionals who already use or plan to use unmanned aircraft systems in their operations.

Each of the three days featured workshops, breakout sessions, networking events, demonstrations, and training for those in attendance, and on the final morning Zenith gave an hour-long demonstration of its TAV-Q28 to many who had expressed interest throughout the week.

Zenith is grateful for this opportunity to have debuted its products and their capabilities to many prospective customers.


Zenith Aerotech Holds Tethered Aircraft Systems Demo Event

The company hosted contingents from its Ohio-based customer, Will-Burt Company, and local first responders the Wintergreen Fire, Wintergreen Rescue, and Rockfish Valley Volunteer Fire departments.

Attendees saw Zenith’s bimotored quadcopter, TAV-Q28, in action amidst sustained 25 mph winds and gusts up to 40 mph. Discussions afterward yielded useful feedback for Zenith regarding specific requirements of the local departments.

Zenith is grateful for everyone’s participation, and looks forward to hosting similar events in the future.
