The system configuration and results are presented for a field experiment on digital maritime satellite communication systems carried out in December 1986, using the INMARSAT Indian Ocean satellite (INTELSAT-V with maritime communication subsystem). The digital communication subsystem used for the experiment consists of a 16-kb/s APC (adaptive predictive coding) voice codec and a rate-3/4 FEC (forward-error correcting) codec using Viterbi decoding for punctured code to utilize the satellite power and bandwidth as efficiently as possible. For the ship earth station, a high-gain antenna with G/T (gain to temperature) of -4 dBK and a low-gain antenna with G/T of -10 dBK were used. The effectiveness of the digital ship earth station system was verified under the actual maritime satellite communication environment with multipath fading.
