Marimsys Satellite Based SystemsTransmission
Satellites are fundamental to almost everything we do at Marimsys. GPS (Global Positioning System) and DGPS (Differential Global Positioning System) based positions form the basis for the precise positioning required for the charts we create, and the positioning of vessels in plotters. Satellites such as ERS 1 / Geosat GM & ERM / Topex / Poseidon gathered the radar reflection data used to calculate the gravity and gravity derived bathymetry charting. We use an entirely different group of low earth orbiting satellites, the NOAA satellites, currently NOAA 12, 14 & 15 primarily for the 1.1 to 4 km visible and infrared light imagery which locates warm and cold currents in the oceans; and secondarily for the ARGOS transmissions hidden away in the same digital imagery. For communications satellites, operating in the VHF, UHF and above bands more and different methods of transferring data and are less expensive each month. The satellite list seems endless now, and is growing monthly. Follow the links below to learn more about how our systems work with the various satellite systems.
High Resolution Picture Transmission (HRPT) Our reception system is Marimsys SIRS-HRPT (Satellite Infrared Reception System - High Resolution Picture Transmission) which is scientific grade NOAA HRPT satellite reception for thermal, climatic and cloud analyses. Typically we mount these systems in the head offices of large fishing companies, in universities and scientific government offices.
Analog Picture Transmission Systems (APT) Our reception system is SIRS (Satellite Infrared Reception System - Analog Picture Transmission) Low cost, use-anywhere NOAA APT satellite reception, typically mounted aboard vessels fishing for tuna, squid and other thermally sensitive species who work too far from land to receive temperature map updates from a shore source.
The Marimsys SHORE BASE System receives satellite positioning, communications and automated data reporting, generally through satellite links. This information is used for the digital and graphical positioning of fleets, to maintain an accessible record of fleet - shore communications and for the management of an enterprise communications backbone. The president can see fleet dispositions on his screen, and review maintenance communications for one vessel for the last week over the internet from his hotel room in Vladivostok. Likewise, your fuel supplier ashore can receive an daily e-mail report update detailing - date, hour and vessel name for fuel needs for the coming week. Or any report in between can be generated.
Customized Data Networks - many types of satellite based marine data networks can be created today. These can range from timed Inmarsat 'C or 'M database updates to a central message and data recording server; to providing fleets with real time video conference calls, multiple line telephone access and large volume data transfers. Our technology for the receipt ashore of marine data, and for its storage, consolidation and report generation is contained within the Marimsys SHORE BASE system. To bring to commercial reality the productivity increasing promise of marine data flows we adapt these systems to client information needs, to gather the necessary data required aboard, to package, encode and transmit it securely, and to present this information in the most productive form to precisely targeted users ashore.
