INNOVATION AT OUR CORE

ULTRA SWaP

Weight-critical airframes need serious RF performance without carrying unnecessary mass. The BluSDR-90-UL Ultra-Light delivers 10 W total RF output from two COFDM transceivers in a 210 g module, giving small platforms the link margin required for long-range missions. Its software defined architecture allows waveform and role flexibility, helping teams tailor the radio to the mission without changing hardware.

MORE INTEGRATED SOLUTIONS

INTEGRATION-READY ON SMALL AIRFRAMES

Small UxV platforms need compact interfaces that connect cleanly to payloads, control systems, and onboard networks. BluSDR-90-UL supports Gigabit Ethernet, dual USB, RS-232 serial data, analogue audio, GPIO, SBUS, and MAVLink through compact JST connectors. As a MANET radio, it forms a MeshUltra-X self-healing network of up to 144 nodes, with Interlink mode for larger systems as airframes and assets join the mesh.

PROVEN RESILIENCE

RESILIENT THROUGH HARSH ENVIRONMENTS

Long-range UxV links must withstand heat, movement, unstable power, and contested spectrum. The BluSDR-90-UL Ultra-Light operates from -20°C to +55°C with additional cooling, accepts a wide 10 to 32 V DC input, and supports adaptive modulation and self-healing routing to keep traffic moving as conditions change. DES as standard and optional AES128/AES256 encryption help protect data across MeshUltra waveforms.
