The new KIV-7HSB is specifically designed to operate in Time Division Multiple Access (TDMA) architectures to provide secure high bandwidth, wide area, networked data exchange via MILSTAR satellites over a broad range of data rates. It fully accommodates all complex handshaking and resynchronization durations encountered during normal TDMA system operations. A direct replacement for the KIV-7, KIV-7HS and KIV-7HSA modules, the KIV-7HSB maintains full interoperability with KG-84, KG-84A and KG-84C, KIV-7, KIV-7HS and KIV-7HSA units currently installed in traditional, non-TDMA, applications.
