Narrowband Military Satellite Communication

Definition/Scope: Military satellite communications (or milsatcom) systems are typically categorized as wideband, protected, or narrowband. Narrowband systems emphasize support to users who need voice or low-data-rate communications and who also may be mobile or otherwise disadvantaged (because of limited terminal capability, antenna size, and environment. In the past, the term "narrowband" implied data rates of less than 64 kilobits per second, but a higher boundary could apply in the future as higher data rates to small terminals become possible. Mobile and other small terminal users depend on high-power, low-data-rate satellite systems to receive data via broadcast (as in the Navy’s Fleet Broadcast) and for two-way communications. Narrowband needs—generally transmitted in the ultrahigh-frequency (UHF) range—are supported by the UFO constellation, which will be replaced by a component of the Advanced Narrowband System.
