An analysis of cellular telephone and INMARSAT systems for providing radio data link computer communications for US Navy vessels

Abstract

This thesis examines radio frequency data link computer communications systems with emphasis on their potential application to ship/ shore communications. Covered are two systems that experts believe hold the most promise for DoD application, International Maritime Satellite (INMARSAT) and cellular radiotelephones. An analysis of system capabilities, cost, and future potential is performed for each, and then the two systems are compared. In addition, a thorough discussion of the security issues for each system and final conclusions/recommendations are presented. The conclusions suggest that increased cellular radiotelephone usage vice INMARSAT by fleet units would optimize fleet readiness and improve supply system performance. Based on these conclusions, this author's recommendation is that all Navy ships be equipped with a cellular telephone system, while all aircraft carriers and amphibious aircraft carriers be equipped with both cellular and INMARSAT systems.
