WDL-45/X

WBDL LOS IN KU BAND

The Wide Band Data Link Line-of-Sight (WBDL LOS) is an avionics wireless communication system for downlink streaming of broadband ISR data (Intelligence, Surveillance, Reconnaissance e.g. Synthetic Aperture Radar, high resolution digital video, analog video) and two-way transmission of Ethernet TCP/IP data, sensor control, mission control, and ATC voice.

Operational applications of the WBDL LOS span through a wide range of manned and unmanned platforms, including tactical UAVs, High and Medium Altitude - Long Endurance UAVs (HALE / MALE), Helicopters, and other ISR platforms.

The WBDL LOS product operates in the Ku radio band (15GHz). However, its modular design supports customizations to other radio bands, e.g. the C band (5GHz).

The WBDL System is composed of an Airborne Data Terminal (ADT) and one or more Ground Data Terminals (GDT), and operates in line-of-sight conditions at very long ranges by means of two-axis directional antennas automatically tracking the aircraft motion.
