StratumFive offer a range of advanced security alert, vessel monitoring, and fleet tracking services compatible with standard Inmarsat C and Mini C installations, providing significant operational value for ship operators who do not wish to install additional dedicated SSAS/tracking hardware solutions.


Inmarsat C  Services

The vast majority of commercial vessels worldwide are equipped as standard with a range of Inmarsat C equipment for GMDSS, communication and/or SSAS purposes.  StratumFive are able to remotely programme (over satellite) this existing equipment to transmit position reports at frequencies to suit operational monitoring requirements.  If the Inmarsat C equipment is SSAS enabled, StratumFive are able to supplement the tracking services by pointing SSAS alerts to our comprehensive alert management module, forming a consolidated and sophisticated vessel security monitoring and fleet tracking solution.


Inmarsat C Alert Service

Existing Inmarsat C and Mini C SSAS equipment can be integrated with our feature rich OTiS software, receiving and directing all Ship Security Alerts to the company security officer, competent authorities, regional co-ordinationcentres, high risk patrols and/or flag authorities via priority email and SMS. By integrating your SSAS into OTiS there is no need to have multiple recipient addresses stored and maintained at the terminal end. Furthermore OTiS will be able to configure and control SSAS terminal tests in a supervisory status, reducing time and resources necessary during periodical maintenance. OTiS also enables management and addition of unlimited SSAS alert recipients and the ability to remotelyreset a terminal in alert.


Inmarsat C Tracking Service

Stratum Five offer global satellite tracking for any vessel equipped with standard Inmarsat C or Mini C installations.  Terminals are remotely programmed over satellite (with no action required by vessel crew), to automatically transmit any frequency of daily position reports, inclusive of position course and speed. The frequency of position reports can be automatically adjusted from once a day down to 15 minute intervals (96 reports per day), to suit any routine operational or emergency vessel monitoring requirements. All position reports are instantly displayed via our sophisticated online tracking and information software, OTiS.  See ‘software’ for further details on the capabilities of OTiS and the significant fleet management benefits available.


Inmarsat C Online Software

Instantly displays security alerts and automatic position reports derived from the existing vessel equipment and referenced against real time location based information, to provide users with a detailed view of a vessel’s movements and performance, together with a range of configurable email notification services. OTiS also correlates meteorological observations, forecasts, tropical stormwarnings and piracy activity against vessel positions, serving a complete fleet tracking and optimisation solution. The comprehensive ship security alert management module offers alert messages and recipient list control as well as simplified testing functions with audit trails.
