Sentinel: The Future of Tethered Drone Technology

At the DSEI 2023 event in London, Drone Evolution unveiled Sentinel, a groundbreaking or Unmanned Aerial Vehicle (UAV). Crafted in the UK, this advanced system promises to revolutionize surveillance and reconnaissance tasks, boasting features that set it apart from its counterparts.

The Sentinel Advantage

Unlike traditional systems, Sentinel comes with an integrated Steatite MPU5 MESH radio, transforming it into an airborne rebroadcasting hub. This ensures heightened surveillance capabilities for real-time situational awareness. Impressively lightweight, the Sentinel tether system offers faster deployment than conventional mast options. Sentinel's applications are vast, perfect for intelligence, surveillance, reconnaissance, force protection, and event security.

The Sentinel is equipped with Drone Evolution's innovative Freedom Power Supply Unit (PSU), taking power efficiency to new heights. This exceptional PSU can produce an output of 100V–500V from a mere 12V or 24V vehicle power supply. Consequently, Sentinel can hover at 50m for an uninterrupted 6 hours, possibly longer. Notably, Sentinel stands out as the singular system that operates straight from a 12v or 24v power source without needing an inverter or generator. Its superior weatherproofing and wind resistance ensure long-lasting performance in the most demanding conditions.

In a statement from the press release, Toby Townrow, Communications Director at Drone Evolution, highlighted the drone's innovative design: “Tethering a drone to a ground power source allows the system to be in the air for periods far beyond conventional battery life. Sentinel really is a game changer; it can be deployed without advanced pilot skills and has the potential for secure communications and overcoming blackspots. Additionally, Sentinel can take your sensors to greater heights than a standard temporary mast system can ever achieve.”

Sentinel: The Future Of Tethered Drone Technology

Seb Leaver, Steatite's Business Development Manager, voiced a similar sentiment, “The combination of Drone Evolution's Sentinel system and the MPU5 Radio System provides a solution to a challenge our clients have had for a long time.”

Sentinel, with its unique features and capabilities, is poised to set new standards in the world of tethered , addressing longstanding challenges in the industry.
