The Air Force normally handles the military’s space efforts but the Navy is responsible for the military’s ultra high frequency narrowband satellite communications systems.
MUOS is comprised of a satellite constellation, a ground control and network management system and a waveform for user terminals.
The Navy says the system supports mobile and fixed-site terminal users.
Once complete, the constellation will include four geosynchronous satellites and one on-orbit spare.
The Navy expects the new constellation to provide more than 10 times the system capacity of the current constellation.
UHF satellites are one of the military’s tools for combating jungle foliage, bad weather and urban settings.
