XM2 | EON800 Tether System for Freefly Systems Alta X | Heavy Lift UAV Tether System | XM2

Key Benefits

Unlimited Mission Endurance

Operate for hours or days without battery swaps. The EON800 delivers continuous power from the ground, eliminating downtime and enabling persistent aerial operations that battery-powered UAVs simply cannot match.

Mission-Critical Reliability

A hard-wired power and data link removes RF dropouts, battery degradation, and thermal limits. You get predictable, stable performance in environments where failure is not an option.

Multi-Payload Capability Without Compromise

Eight fibre-optic cores enable simultaneous command, control, and payload data streams — allowing operators to run multiple sensors, cameras, or communication systems without bandwidth contention or signal degradation.

Higher Payloads, Longer Loiter

By removing onboard batteries and supplying up to 4500 watts of power from the ground, the Alta X can carry heavier payloads for extended periods — unlocking use cases previously considered impractical or impossible.

Secure, Interference-Free Data Link

Fibre-optic communication provides a highly secure, low-latency connection that is immune to RF congestion, jamming, and interference — ideal for sensitive, regulated, or high-risk operations.

Rapid Deployment & Integration

Designed as a plug-and-play solution for the Freefly Systems Alta X, the EON800 integrates tool-lessly with minimal configuration, reducing setup time and allowing teams to deploy faster.

Designed for Professional Operations

Rack-mountable ground station hardware, vehicle integration options, and ruggedised components make the EON800 suitable for long-term field deployment across broadcast, surveillance, emergency response, and defence environments.

Scales With Your Mission

Available in multiple tether lengths with custom options, the system adapts to different altitudes, sites, and operational constraints — from urban monitoring to wide-area coverage.


XM2's EON800 is an Australian-made, tethered data and power solution for heavy-lift drones. Developed by XM2 Labs, compatible with a range of drone platforms and designed to be modular, each component of the EON800 tether system has been optimised for integration.

EON800 Tether System for Freefly Systems ALTA X | EON800-AX

Expanding the capabilities of the Freefly Systems ALTA X, the EON800 is a plug and play tether solution designed to power Freefly Systems Alta X. This ALTA X Tether system provides the worlds toughest heavy lift UAS with infinite flight time and eight fiber optic cores, for multi-payload connectivity.

EON800 Tether Ground Station

The EON800 Tether Ground Station provides the drone with infinite flight time, supplying up to 4500W of power to the UAS and a myriad of payload combinations. The Tether Ground Station is rack-able, allowing the unit to be mounted within vehicles, portable rack cases and any structures with mounting rails. MAVlink Connectivity between the Drone and the Tether Ground Station provides secure, wired control of the UAV.

UAS Tether Cable

Eight fibre-optic cores and two conductors are embedded within the provided XM2 UAS Tether Cable. One fibre is dedicated to command and control of the aircraft and seven separate dedicated payload fibres are available for payload communication. The Tether Cable is manually managed, and available in two altitude lengths: 60m/200ft and 120m/400ft. Custom lengths are also available.

EON800 Tether Ground Station for Freefly Alta X

Alta X is approved under the Blue sUAS 2.0 program, and custom configured to support a variety of mission requirements; the Freefly Systems Alta X accommodates a variety of integrated sensors and third-party payloads. This creates vast potential and opportunity within the telecommunication, live broadcast, surveillance, public safety, emergency response and defence industries to name a few. Continuous tethered flight with truly massive payloads is something that until now, has not been possible.
