The SkyWave PoleStar DSAS Mk2 is a Ship Security Alert System (SSAS) designed to meet SOLAS Chapter XI-2/6 and ISPS Code requirements for maritime security . This robust, self-contained unit integrates an Inmarsat IsatData Pro satellite transceiver with power management and backup batteries, providing reliable covert security alert transmission from vessel to shore .
Key Features & Benefits
Covert Silent Alerting
When activated, the DSAS Mk2 transmits a silent security alert directly to designated recipients—including flag states, ship owners, and company security officers—without raising any audible or visible alarm onboard or alerting nearby vessels . This covert operation ensures crew safety during piracy, armed robbery, or terrorist incidents.
Global Satellite Connectivity
Utilizing the Inmarsat IsatData Pro network via the global I-4 satellite constellation, the system provides worldwide coverage with faster message delivery and longer message capacity compared to legacy systems .
Extended Backup Power
The unit features an internal battery pack providing 5-6 days of independent operation in full reporting mode, ensuring continued functionality even when main vessel power is disrupted .
