Study and Design of the Data Transmission System for Marine Telemetering

Effects of the electrical conductance characteristics as well as of the terrain features, both marine and over land, upon the propagation of groundwave and skywave are analyzed. Carrier-frequency range and code ratio suitable for a marine telemetering system is presented. The results of calculation for the sensitivity of telemetering receiver and its error probability are given, taking 2 identical bits from 3 corresponding bits received, with 3 fold retransmission.
