Mission configurable tethered UAS for ISR, communications, and lightweight mission payloads, built for rapid deployment and continuous operation.
Eliminates battery-cycle downtime for persistent, always-on operation.
Sized for rapid setup, vehicle transport, and constrained sites.
Supports EO/IR, communications, and lightweight sensor payloads.
High-bandwidth, low-latency video and telemetry through the tether.

Persistent ISR
Communications Relay
Border & Perimeter Security
Designed for persistent operation without battery swaps or routine recovery cycles.
Validated through extended-duration flight testing in operationally relevant conditions.
Modular aircraft architecture enables rapid inspection, component replacement and return to operation.
Continuous airborne power delivered through the tether from the Ground Power Unit, eliminating battery-cycle downtime.
Fiber-optic data path for video and telemetry, with tactical radio payload options for mission communications relay.
Ethernet, IP, and MAVLink support for integration with ground networking and mission systems.
From fixed facilities to mobile and rapid field operations, the same Quad-L platform adapts to your mission and environment.




Quad-L aircraft, payload, telemetry, and video are managed through ZATQGC, Zenith's mission control software.
