«Ray» Radio System
A family of wireless systems for UAV HD video and telemetry transmission, with data rates up to 30 Mbps. The product line includes models with varying operational ranges, from the MK-22 (22 km) to the long-range MK-150 (150 km).

MK-22 / МК-55
These radio modems offer identical high data rates (up to 30 Mbps) but differ in range: the MK-22 covers up to 22 km, while the MK-55 extends to 55 km

МК-100 / МК-150
Similarly, these modems share the same high-speed link (up to 30 Mbps). The MK-100 provides a range of up to 100 km, and the MK-150 reaches up to 150 km
Key Features
Long-Range Data Transfer
A reliable system ensuring stable wireless connectivity with very low latency. Capable of streaming two video feeds simultaneously at a total bitrate of up to 30 Mbps.
Superior Anti-Jamming Performance
Featuring an optimized operating frequency and advanced transmission protocols, the system offers high resilience against electronic countermeasures (ECM), ensuring a reliable communication channel in contested environments.
Rugged & Field-Proven Design
With over three years of successful operation in diverse conditions, the system is built to last. The ground station features a durable housing, clear link status indicators, and an integrated tripod mount.
Versatile Compatibility
Supports point-to-point operation and is designed for easy integration into modern drone systems. Fully compatible with the «Control-3» ground controller.
