STN ATLAS DEBEG 4400B DGPS DISPLAY MONITOR 3508 102 19580 V34 LEICA GMDSS

The STN ATLAS DEBEG 4400B is a professional-grade, integrated Differential GPS (DGPS) navigation and display unit designed for use in demanding maritime environments, likely aboard naval vessels, large commercial ships, or specialized research vessels.

Key Features and Characteristics:

1. High-Precision Positioning: At its core, it is a DGPS receiver, utilizing correction signals (likely from maritime beacon networks or satellite-based augmentation) to provide positional accuracy significantly better than standard GPS. The mention of Leica suggests the possible use of high-quality GNSS receiver technology renowned for its reliability and precision.
2. Integrated Display Monitor: Serves as the primary navigation display, showing the ship’s position, course, speed over ground (SOG), course over ground (COG), and other relevant data on a dedicated screen.
3. GMDSS Compliance/Integration: A critical feature, indicating the unit is part of the vessel’s safety architecture. It likely provides highly accurate position data for automatic inclusion in Distress Alerts (e.g., for the Digital Selective Calling – DSC – system within GMDSS), ensuring rescue services receive the most precise location possible in an emergency.
4. Military/Professional Build: The combination of STN ATLAS and DEBEG, along with the long-form part number (3508 102 19580), points to a ruggedized design built to withstand the marine environment and meet stringent military or commercial classification society standards (like SOLAS).
5. System Component: It was likely part of a larger integrated bridge system (IBS) or navigation suite from STN ATLAS, interfacing with radars, electronic chart displays (ECDIS), autopilots, and GMDSS communication consoles.

Typical Applications:

• Warships (frigates, corvettes, auxiliaries)
• High-end commercial vessels (research ships, survey vessels, large yachts)
• As part of a comprehensive GMDSS station for safety-critical positioning.

Breakdown of the Components

• STN ATLAS: The manufacturer. STN Atlas was a major German company (now part of Raytheon Anschütz) specializing in marine electronics, particularly for warships and high-end commercial vessels.
• DEBEG 4400B: This is the model number. DEBEG was another renowned German marine radio company, often integrated with ATLAS systems. This strongly suggests the unit is a DGPS (Differential GPS) receiver and display.
• DGPS DISPLAY MONITOR: Confirms the unit’s primary function: to receive Differential GPS signals (for enhanced positional accuracy) and display navigation data.
• 3508 102 19580: This is almost certainly a part number, serial number, or NATO stock number (NSN). The structure is typical for military or professional maritime spare parts identification.
• V34: Likely refers to a hardware or software version (Version 34) of the unit.
• LEICA: This is interesting. Leica Geosystems is famous for high-precision GPS/GNSS surveying equipment. Their inclusion here suggests this unit may incorporate Leica’s core GNSS receiver technology or antennas for highly accurate positioning, packaged by STN ATLAS for marine use.
• GMDSS: Stands for Global Maritime Distress and Safety System. This indicates the unit is not just a navigation tool but is integrated into or compliant with the mandatory international safety communications system for ships. It may have interfaces or functions related to distress alerting or safety communications.
