Sailor TT-3020C Inmarsat-C / GPS Transceiver
Overview
The Sailor TT-3020C is a robust and compact GMDSS (Global Maritime Distress and Safety System) transceiver, designed for global Inmarsat-C satellite communications with optional GPS integration. It supports full SOLAS/GMDSS functionality, enabling distress calling, position reporting, messaging, and data services across oceans. Marinsat+2Marinsat+2
Key Features
-
SOLAS / GMDSS Compliance: Fully meets international safety standards, including ability to issue distress calls (Inmarsat CN 114).
-
Multi-mode Data & Messaging: Supports e-mail, Telex, X.25, fax, and mobile-to-land data.
-
Position Reporting & Fleet Management: Enables automated position reports to multiple destinations with configurable intervals and multiple DNIDs (destination identifiers).
-
Optional Integrated GPS: A 12-channel GPS module is available, enabling the device to derive its own positional data.
-
Compact & Power-Efficient: The transceiver is designed for minimal size and power, making it suitable for installation in constrained spaces.
-
Flexible Peripheral Support: Includes multiple control ports, NMEA-0183 interface, ArcNet network capability for printers and alarms, and support for remote alarms, remote printing, and power units.
-
Antenna Integration: Often supplied with or compatible with the TT-3005M omni-directional antenna, combining Inmarsat-C and GPS in one unit.
