Built for the Future

The ACSS commercial-off-the-shelf Identification Friend or Foe (IFF) Transponder (XS-950SI) was selected and certified by the U.S. Navy as the transponder of choice for C-130, VP-3, C-12, and C-2 aircraft. Boeing selected the XS-950SI for the 767 Global Tanker Transport for domestic and international tankers, and the U.S. Army selected the XS-950SI for the UC-35 Citation Ultra. The XS-950SI is also gaining an international market presence on such platforms as the Embraer 135 and 145. Maximizing the use of commercial-off-the-shelf technology, the XS-950SI enables coordinated and simultaneous Mode S and IFF capability that is necessary for TCAS II operations. The FAA certified XS-950SI is a full-featured transponder implementing all currently defined Mode S and IFF functions, including DO181B Elementary & Enhanced Surveillance, GPS position, velocity, Flight ID extended squitter with built-in growth for future IFF Mode 5.
