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.

The WDL-45/S version complies with NATO STANAG 7085 Edition 3
The non-NATO version (WDL/45E)
operates a proprietary radio protocol for non-NATO customers
Robust and secure digital waveforms,
with data rates up to 45 Mb/s in downlink and 2 Mb/s in uplink
Strong FEC techniques, configurable data rates, and Spread Spectrum waveforms improve the operational ranges and robustness of communication services

Automatically controlled high-gain directional antennas on board and on ground
ADT processes in real time the aircraft Navigation data
GDT implements monopulse tracking technique, ensuring fast link setup and dynamic antenna control
Ground Data Terminal includes a remote Interface Unit, which may be installed up to 1.5 km away from the tracking antenna

Modes

Point-to-Point
Broadcast (with omnidirectional antenna at the aircraft)
Multi-user: advanced Uplink waveform with multiple GDTs
Relay mode: provision, implemented on request.
