Navy Multiband Terminal System : High bandwidth submarine, shore-based, and shipboard satellite communications
Raytheon and the Navy have successfully completed formal testing of the Navy Multiband Terminal (NMT) satellite communication system. NMT is a system of submarine, shore-based and shipboard communications terminals for the transformational satellite communications component of the U.S. Navy's FORCEnet concept. NMT provides the bandwidth efficiency that allows naval information networks to extend seamlessly from individual ships and submarines to other networks around the globe. NMT replaces three separate systems currently deployed in the U.S. Navy, extending the submarine and shipboard capability from Extremely High Frequency waveforms to Advanced Extremely High Frequency and providing global broadcast system, X- band and Ka-band services. Time Division Multiple Access refers to signal protocols used in many cell phone services. Raytheon's new, advanced eXtended data rate wave form performs both network and point-to-point anti-jam communications at data rates up to eight megabits per second. This performance provides more than four times the current protected throughput. The NMT can operate on polar-inclined orbit satellites to provide full global connectivity for submarines even in the polar extremes. Nanosecond timing of antenna handovers under harsh at-sea conditions ensure uninterrupted shipboard communications. The NMT can automatically establish Internet Protocol connectivity using the Navy's Time Division Multiple Access Interface Processor for bandwidth efficiency.
