Our products have been successfully deployed on dozens of different unmanned platforms around the world.

Robust Communication Links

communication modem

Our communication data links use a unique hybrid of OFDM and spread spectrum (SS) communications methods. The OFDM_Flexi technology makes it possible to combine multiple channels into a single link, with control and telemetry channels protected by a robust SS profile, and a high-speed video channel that takes advantage of the superior performance of OFDM.

OFDM_Flexi uses a sophisticated matched filter detector that supports link synchronization for input signal-to-noise ratios (SNR) down to −17 dB. Unmatched by almost all OFDM wireless technologies based on open standards as well as many proprietary technologies, our OFDM_Flexi can maintain robust link synchronization in conditions where many other wireless technologies fail.

Sophisticated algorithms collect and rearrange components of dispersed signals under NLOS conditions, applying error correction and ensuring reliable control and crystal-clear transmission even at flight speeds of up to 800 km/h.

3D Link – Bi-Directional Data Link

Radio link for UAV control and video transmission

Drone data link communications3D Link is a bi-directional data link for drones and robotics that combines separate control, telemetry and real-time Full HD video channels into one convenient device, doing away with the need for separate modems. With a throughput of up to 64 Mbps, it is ideal for both LOS (line of sight) and NLOS (non-line of sight) applications.

Drone network data linkThe full-duplex modem supports point-to-point, point-to-multipoint and relay networking topologies.

Multiple drones can be controlled from, and their video feeds received by, a single ground control station (GCS) or conversely a single drone can be controlled by and communicate with several stations.

A unique retransmitting mode allows the radio to provide range extension even in urban and cluttered areas, allowing users to receive video directly from a distant drone and from other nodes in the relay at any time.

3D Link is available in two versions: regular, and 3D Link HP which features a transmitter with enhanced output power for greater range.

3D Link

3D Link HP

All our radios are supplied with SDR_Surfer, a powerful software tool that allows easy integration of almost any third-party ground control station application via a UDP/TCP connection. SDR_Surfer allows users to configure wireless link parameters, monitor and log statistics, measure distance between ground station and vehicle, and more.
