GuRu Wireless

GuRu Wireless is the developer of an innovative wireless RF power beaming technology that enables tactical drones to fly indefinitely, enabling truly persistent ISR (intelligence, surveillance, and reconnaissance) for critical defense and security operations.

The company’s solutions enable extended missions without the need for tethers or to land for battery charging and swapping, massively reducing disruption and manpower requirements.

Cutting-edge wireless power for unprecedented ISR capabilities

Developed for mission-critical use cases, GuRu Wireless power beaming systems enable tetherless persistent flight for small Unmanned Aerial Systems (sUAS). The innovative power beaming systems extend sUAS endurance from minutes to hours or days through wireless in-flight battery recharging, eliminating physical connections while supporting ISR and communications at operational altitudes.

Continuous, uninterrupted access to the sUAS payload enhances mission effectiveness and reduces the risk to warfighters by eliminating the need to land, recharge, swap batteries, or manage tethers. This autonomous in-flight recharging capability enables UGV/UAS mission pairing, expanding options for first-encounter and counter-UAS missions.

How GuRu Wireless power beaming works

With a unique combination of beam shaping and smart lensing, GuRu’s wireless energy transfer technology has overcome the limitations of previous methods to provide in-flight recharging for mission-critical drones.

GuRu’s system uses a ground-based Generation Unit (transmitter) built around a software-steered 24GHz phased array to convert electrical power into tightly focused RF beams.

Using digital beamforming and proprietary GuRu RF Lensing®, the system forms, steers, and concentrates energy in real time to deliver power efficiently at range while suppressing sidelobes. A compact onboard Recovery Unit (receiver) locks onto the beam, converts RF energy into regulated DC power, and feeds the sUAS battery or power management system. Closed-loop tracking maintains alignment with moving targets, and the system can time-share or multiplex beams across multiple receivers to to track and recharge multiple targets.

This capability is enabled by GuRu’s scalable Long Range Wireless Power Beaming (LRWPB) platform, which integrates power- and weight-efficient receivers into purpose-built aerial platforms. The result is persistent flight operation for applications including border security, base protection, convoy operations, maritime surveillance, and critical infrastructure monitoring.

The technology has currently achieved TRL 6, and has been successfully demonstrated to the US Army and Marine Corps, achieving over 96 hours of continuous drone flight with recharging at 200 feet.

Wireless power for defense & national security applications

While small UAS have become a critical tool for ISR and security, they are fundamentally constrained by battery life. Their limited flight time creates mission gaps, leaving defense forces vulnerable in persistent threat environments and requiring more manpower and workload.

GuRu Wireless’ mid-air power beaming solution enables drones to stay aloft indefinitely, providing complete and continuous overwatch without the need for battery replacement or mobility-restricting tethers. Unmanned aircraft can recharge onboard batteries while airborne, and are free to switch seamlessly between loitering and extended mission excursions.

This game-changing technology is ideal for securing and protecting a variety of assets and facilities, including:

• Forward operating bases
• Convoys
• Headquarters
• Ports and harbors
• Critical infrastructure
