A complete GMDSS training station integrating 15 communication and safety systems, including VHF/MF-HF DSC, Inmarsat-C, FleetBroadband, Iridium, NAVTEX, EPIRB, SART, SSAS, LRIT, a distress alarm panel, and Aero VHF.

Bridge navigation equipment โ including radar/ARPA, ECDIS, AIS, and GPS โ is integrated into the same training environment, enabling trainees to manage communications and navigation within a realistic operational scenario.

Trainees can perform distress, urgency, safety, and routine communications, including DSC alerting and acknowledgement, satellite messaging, NAVTEX/EGC safety information, and live voice communication. Communication range is realistically modelled by equipment and propagation conditions, ensuring out-of-range stations cannot communicate.

The instructor can control vessels, positions, courses, speeds, exercise timing, and equipment faults across a networked classroom. Every communication and alert is automatically recorded with station, equipment, frequency, and time, supporting replay, assessment, and competency-based scoring.
Install on any iOS or Android device. Configure vessel MMSI, vessel name, and regional frequency settings. Works offline instantly.
Trainee practices distress alerts, urgency pan-pan, safety securite, and routine calling procedures with full voice simulation.
Training log reviewed. All procedures scored against STCW requirements. Certificate of competency report generated.
