S-TADIL J
S-TADIL J, or Satellite TADIL J, is a real-time Beyond Line-of-Sight Tactical Digital Information Link supporting the exchange of the same J Series message set that is implemented on Link-16 via the Joint Tactical Information Distribution System. S-TADIL J provides for robust continuous connectivity between Navy ships that are beyond JTIDS line-of-sight transmission range. S-TADIL J is designed to support and significantly improve long-range TADIL connectivity between widely dispersed fleet operational forces. With the deployment of S-TADIL J, operational units will have three possible data link paths that can be used to support multi-ship data link-coordinated operations. S-TADIL J supports the same levels of surveillance and weapon coordination data exchange provided by Link-11 and Link-16. The TADIL J message standard is implemented on S-TADIL J to provide for the same level of information content as Link-16.Change of terminology
In the US, the term Tactical Digital Information Link is obsolete and is now more commonly known as Tactical Data Link .
