ZAT Quad-8 is designed and built in the US and is NDAA compliant. Quad 8 brings quadcopter reliability to another level with two motors and propellers on each of its four arms. The redundant propulsion systems means that the unit can safely land even after the unlikely motor loss.

The closed fuselage structure protects internal components from rain and dust. Due to its foldable arm design, the ZAT Quad-8 allows for easier transport. Quad-8 supports tethered operation with various payloads such as communication devices, EO/IR cameras, cUAS radars, illumination panels or other custom devices up to 20 lbs.

The ZAT Quad-8 platform delivers performance, redundancy, and reliability for mission critical applications.

Zenith QGC software is a ground control station software which is dedicated to tethered drone operations, designed for the operators to proceed successful missions. In a basic operation, operator presses take-off button, enters flight altitude to the slider and confirms the take-off. Tethered drone system will automatically take off and hover in the altitude.

Operator can navigate with clicking on the map and use go to function, operator can also yaw to the position, all the payload data and controls are implemented on the software. For ending the mission operator clicks to the land button and confirms the action. All the safety procedures and fail safe options are automated, operator does not need to take action for these applications.

Unique Functions

Power Compensation

Zenith ground station compensates the voltage drop occured through the cable in order to carry high payloads in higher altitudes.

High Thrust to Weight Ratio

Zenith tethered drones have high thrust to weight ratio in order to provide a reliable flight with 400 feet of cable even in windy weathers.

Made in U.S.A

All Zenith tethered drone systems are made in U.S.A. and they are NDAA compliant. Our products are widely used by government customers.
