INMARSAT-C Activation – Professional Setup & Marine Support by SEANAV

INMARSAT-C Activation is a crucial process that ensures maritime communication systems are fully operational and GMDSS-compliant. Whether you’re commissioning a new vessel or upgrading communication equipment, proper activation is essential for global tracking, messaging, and distress alerting. At SEANAV, we offer expert INMARSAT-C activation services tailored for vessels operating worldwide.

What Is INMARSAT-C Activation?

INMARSAT-C is a satellite-based communication system used for text messaging, distress alerts, EGC (Enhanced Group Call), and polling. Activation involves programming the terminal, registering with a Land Earth Station (LES), and configuring the Data Network ID (DNID) to allow seamless transmission. It is a regulatory requirement under the GMDSS framework.
