ABSTRACT (maximum 200 words)
Mobile Satellite Services (MSS) need to be integrated into Naval Cominunications. DoD SATCOM military-
owned systems fall well short of meeting DoD SATCOM requirements in general and mobile SATCOM specifically.
This thesis examines DoD SATCOM requirements, especially those affecting communications on the move. From these
requirements, three systems ~ Inmarsat, Iridium and Globalstar ~ are identified and evaluated for potential use in Naval
Communications. An overview of space communications and each ofthe three systems is provided to identify general
operational capabilities, system strengths and system weaknesses. The Naval narrowband functional requirements
process is explored and DoD SATCOM and Commercial MSS ability to satisfy those requirements is assessed.
Potential Naval MSS communications missions are examined and possible DoD enhancements are considered for each
system as well as the impact these enhancements will have on each system. Recommendations are provided as to which
Naval communications missions are best suited forthese enhanced MSS.
