British unmanned systems developer Evolve Dynamics has introduced a new tethered drone solution designed to deliver continuous, jam-resistant aerial surveillance for up to 48 hours.
The new system, called Infinity Tether, is compatible with the company’s Sky Mantis 2 and Wolfe unmanned aerial systems (UAS) and is engineered to provide persistent overwatch, perimeter security, and intelligence, surveillance, and reconnaissance (ISR) support in GPS-denied or electronic warfare (EW) conditions.
Evolve Dynamics describes Infinity Tether as a rugged, lightweight, and intuitive platform capable of holding a fixed vantage point at adjustable altitudes of up to 100 meters. Its primary appeal is sustained endurance: when deployed, the tethered drone can remain airborne for more than 48 hours continuously, far surpassing the endurance limits of traditional battery-powered drones.
“Stop worrying about battery life and start focusing on the mission,” the company said, underscoring the system’s focus on operational continuity and mission readiness.
One of Infinity Tether’s core features is its secure, hard-wired 100 Mbps data link, which ensures a reliable, high-speed ISR feed even under intense jamming or in radio-denied environments. The hard-line connection enables radio-silent operations and provides a dedicated data pathway that cannot be disrupted by conventional electronic warfare techniques.
The system’s design allows operators to maintain persistent aerial observation of a designated area — such as a base perimeter, critical infrastructure site, or forward operating position — without the logistical challenges of frequent battery changes or the vulnerabilities associated with wireless data transmission.
For military users, this capability provides a decisive edge in complex environments where electronic warfare, GPS spoofing, and communications denial have become central features of modern conflict.
Infinity Tether is also equipped with a unique “Hot-Drop” feature, allowing operators to instantly transition from tethered mode to free flight if mission requirements change — such as when a target needs to be pursued. Once released, the drone can continue untethered operations for an additional 30 minutes using onboard battery power.
This dual-mode flexibility combines the persistent endurance of a tethered platform with the agility of a free-flying drone, giving operators more tactical options in fast-changing situations.
The system’s hot-swappable design allows rapid replacement of the standard Sky Mantis battery, and it can be powered directly from mains electricity or a field generator. Its environmental rating (IP54) ensures operational reliability in harsh conditions, with temperature tolerance from -30°C to +55°C and wind resistance up to 22 knots.
Evolve Dynamics says the Infinity Tether is engineered for scenarios where conventional drone operations face limitations. Its ability to operate in radio-silent, dual-path communications modes and deliver secure ISR data in EW-contested or GPS-denied environments makes it particularly suited for modern battlefields, border security, and sensitive surveillance missions.
With a total system weight of 13.2 kilograms and a single-cable power-and-data line capable of reaching 100 meters, the Infinity Tether can be quickly deployed for fixed-site monitoring or integrated into broader ISR operations as a persistent node.
The system is expected to enhance the effectiveness of both military and homeland security missions, particularly those requiring long-duration overwatch or continuous sensor coverage in complex operational theaters.
