Cellular Satellites: Joint Communications With Integrated Acquisition.

摘要

It s a familiar image: a Soldier crouching with a radio, next to a spidery antenna pointing skyward to reach a distant satellite. But that view of military communications is on the verge of change being replaced by troops rapidly exchanging data while moving seamlessly around the battlespace. This progress is possible due to the Mobile User Objective System (MUOS), the next-generation narrowband military satellite communication system that will support worldwide, multi-Service users in the Ultra-High Frequency (UHF) band. MUOS will use Earth-orbiting satellites as the equivalent of cellphone towers in space, providing smartphone-like service that keeps users connected while on the move and in challenging urban, jungle or mountainous terrain. As the current UHF satellite constellation reaches the end of its life, MUOS will replace it with a communications capacity that is more than 10 times greater.
