C-Link Naval Link System
The C-Link Tactical Data Link module provides various Tactical Data Links for NATO customers and Terma Link for non-NATO customers. Multil-ink solutions are also available.
Introduction
Tactical Data Link (TDL) is used to ensure exchange of a Common Operating Picture (COP) between cooperating units. Whether this COP being airborne, sea- or ground- based, a TDL is required to exchange real-time tactical data securely and reliable. TDL enables interoperability working in an international environment.
C-LINK is the collective name for the various TDL supported by the Terma C-Flex Command & Control system.
C-LINK can be used onboard different platforms, such as: ships, helicopters, Maritime Patrol- and Surveillance Aircrafts, Headquarters or Operation Centres.
