” INMARSAT C Activation – Seamless Global Maritime Communication

INMARSAT C is a trusted and widely used maritime communication system that ensures safety and efficiency at sea. The activation of INMARSAT C is a critical step for vessels to comply with international maritime regulations, including GMDSS (Global Maritime Distress and Safety System). At SEANAV, we offer professional INMARSAT C activation services to ensure vessels remain connected, compliant, and secure across global waters.

With decades of experience in maritime satellite systems, SEANAV ensures a smooth activation process, from configuration to registration with the relevant Maritime Rescue Coordination Center (MRCC). Whether your vessel is newly equipped or undergoing system reactivation, our technicians will guide you every step of the way.

INMARSAT C is mandatory for vessels subject to SOLAS regulations. Activation allows real-time communication with authorities, supports distress alerts, and transmits ship data via text and email. Furthermore, it enables the Long Range Identification and Tracking (LRIT) function, required by flag states and IMO.

SEANAV’s INMARSAT C Activation Services Include:

  • Terminal configuration and testing
  • Flag registration and commissioning
  • Message testing and confirmation
  • LRIT conformance testing (if required)
  • Onboard or remote activation support
