S-TADIL J
S-TADIL J, or Satellite TADIL J, is a real-time Beyond Line-of-Sight (BLOS) Tactical Digital Information Link (TADIL) supporting the exchange of the same J Series message set that is implemented on Link-16 via the Joint Tactical Information Distribution System (JTIDS). S-TADIL J provides for robust continuous connectivity between Navy ships that are beyond JTIDS line-of-sight (LOS) transmission range.
