Simple, Reliable, Affordable I-VMS from the global leader

NEMO is the first all-in-one system specifically designed for monitoring and protecting small-scale fisheries. NEMO offers hybrid global connectivity, using GPRS/IoT networks in coastal areas and automatically switching to satellite systems when the vessel moves outside the range of terrestrial networks.

Services range from basic delivery of data collected and processed in CLS’ data center, data integration with client’s fisheries monitoring center and access to CLS’ web platform for data visualization, alert management and customized analytics.
