Inmarsat-C Activation

Inmarsat-C is a two-way packet data service operating between mobile earth stations (MES) and land earth stations (LES). Inmarsat-C uses a small, multi-directional antenna.

The service is approved for use under the Global Maritime Distress and Safety System (GMDSS) and meets the requirements of the Ship Security Alert Systems (SSAS) as defined by the International Maritime Organization (IMO).

Inmarsat-C and Mini C, used for distress and safety communications and fleet tracking, allow the sending and receiving of data messages up to 32 kilobytes. The service works through a storage and transmission method that interfaces with data network transmissions, such as email, SMS, telex, remote monitoring, tracking (location reporting), maps and weather updates, maritime safety information (MSI), maritime safety, GMDSS, SafetyNET and FleetNET services, two-way messaging, data reporting and polling, Safety/Emergency alerts. Voice communication is not possible with Inmarsat-C.

Inmarsat Mini C terminals are the smallest models, with some integrating the antenna and transceiver in the same deck unit, supporting the same communication services as Inmarsat C terminals depending on the model.

All modern Inmarsat C and Mini C terminals include an integrated Global Navigation Satellite Services (GNSS) receiver for automatic position updates at the terminal. This receiver is used for distress alerts (ship’s position, course, and speed), ship position data reporting applications, and selective reception of EGC SafetyNET messages.

Key Features of Inmarsat-C

• Reliable Access to Critical Information: Inmarsat-C provides reliable access to critical information, including position reporting, data monitoring, messaging, and distress calls. Users can rely on this system for accurate and timely communication.

• Compliance with Maritime Safety: Inmarsat-C is fully compliant with the Global Maritime Distress and Safety System (GMDSS), a set of international regulations and protocols designed to enhance safety and emergency response capabilities. The system contributes to the overall safety of maritime operations by adhering to GMDSS standards.

• Flexible Billing: Inmarsat-C offers volume-based billing, making it easy for users to manage their billing according to their usage. This approach provides greater flexibility and cost control.

• Compact Equipment: The equipment required for Inmarsat-C is designed to be lightweight and compact. This feature ensures easy installation and minimizes space requirements on ships or other maritime vehicles.

• Cost Efficiency: Inmarsat-C is compatible with an IP Front End Processor (IP-FEP) that enhances cost efficiency. Additionally, direct access to Inmarsat's Land Earth Station further optimizes operational costs.
