A communication system data logger records data from various onboard communication systems such as VHF, AIS, GMDSS, and satellite phones. Installation ensures that communication activity is logged for monitoring and future analysis. The data logger captures information such as transmission times, signal strength, and system status, providing valuable insights into system performance and helping diagnose issues. It also assists with regulatory compliance, as it can demonstrate proper usage and adherence to maritime communication protocols. Data loggers contribute to improved safety, system reliability, and operational efficiency.
