Common Data Link (CDL) Training
Common Data Link (CDL) Training is intended as a comprehensive introduction to Tactical Data Links (TDLs) and Common Data Link (CDL) for practicing analysts, engineers or those with similar backgrounds. This 2-day long course is also useful as an overview for managers who want to have an insightful talking understanding of the topic.
CDL (Common Data Link) is the DoD’s standard communications waveform for Intelligence Surveillance & Reconnaissance (ISR) in airborne platforms. In supporting this standard, the military has numerous air, sea and ground CDL systems for theater connectivity.
CDL (Common Data Link) can also support space assets that can bring their tactical ISR data directly into the theater, allowing for responsive tasking and collection.
Participants will learn about CDL and concepts behind full-duplex, jam resistant spread spectrum, point-to-point digital links.
Common Data Link (CDL) uses secure protocols along with a full duplex, jam resistant spread spectrum digital data link. CDL is operated by the U.S. Department of Defense (DoD) and U.S. intelligence agencies for wideband real-time downlink transmission of sensor data and real time uplink control of sensor payloads.
