PMW-146-D February 2007 CLASSIFICATION (U) Classified by: PMW-146 Maureen Jackson MUOS Ground System Director Navy Communications Satellite Program Office (PMW-146)

2 Introduction/Agenda MUOS System Introduction Spectrum Usage Ground Segment Architecture Physical Architecture Service Architecture Leveraging COTS Packages Rollout Schedule Summary PMW-146-D

3 What is MUOS? Next Generation communications system replacement for the current UHF Follow On (UFO) Constellation Global voice and data communications via: Four (4) satellite constellation Coverage to ± 65º latitude Simple Bent Pipe operation includes: MUOS payload» 16 beam segmented footprint» Up to 4 Wideband Code Division Multiple Access (WCDMA) carriers per beam Legacy payload (UFO F-11 Heritage)» Single beam horizon-to-horizon footprint Ground System leverages commercial cellular technology PMW-146-D

4 MUOS Key Features Focus on usability Minimized planning operations Priority/Preemptive operation arbitrates in real-time Simply power/dial & communicate Connect to personal computer and go it just works Seamless global mobility Global group communications Connect any set of users, regardless of location User-to-User, User-to-DISN/PSTN Voice, circuit data, packet data Data rates to 384 Kbps Network Centric architecture Future upgradeable The works are on the ground PMW-146-D
