A Comparison of Alternative Transmission Paths for Administrative Data from Afloat Units

Abstract

This thesis considers the problems associated with moving high volumes of administrative data from afloat units to shore commands. It proposes three alternative technologies and compares them on the basis of effectiveness, reliability, ease of use, and cost. All three alternatives are based on collecting data on a shipboard microcomputer, compressing it, and transmitting it to a computer bulletin board system ashore where users can download data via commercial telephone lines. The primary difference between the three alternatives is in the transmission medium used. The first uses military satellite channels. The second uses High Frequency radio. The third uses INMARSAT, a commercial satellite communication system. All three alternatives are capable of effectively transferring data, but the best all-around performance was achieved with the INMARSAT-based system. Further consideration of variants on the system tested is recommended because the development of cost saving measures may make it highly competitive with current methods.
