High precision Environmental Data
The EOS marine module makes the regular EOS-1000 into a Marine version of the EOS-1000. Having a Weather system installed on a moving ship provides it challenges.
Where a land-based station is stationary and pointed towards the North, a moving vessel can travel in any direction and speed. Using the vessel’s GPS Speed and course, the EOS-1000M will calculate True wind speed and direction.
Often Weather conditions are observed different offshore than on land. Due to a lack of offshore environmental observation equipment, up-to-date weather conditions are difficult to tell . Therefore, this system was developed based on the customer’s requests to monitor real-time weather conditions while vessels are underway.
Together with EOS partner Seacoast Marine Electronics, the last installation is currently underway on board three large Ferries as well as one shore based Weather observation system on the East coat of Canada.
How it works
Included in the EOS Marine module is a serial interface module that can receive data from 4 NMEA-0183 navigation devices such as GPS, Gyro compass and speed log. It will also allow NMEA data to be transmitted to two external devices such as our KMR6 or IR761 display as well as other Navigation equipment compatible with the NMEA-0183 / IEC61162 standards.
The EOS Serial interface uses 4 galvanically isolated ports reducing the risk of ground faults.
For extensive data review, an additional 15” or 19” touch screen monitor can be added to display comprehensive weather data from the own vessel, or, in case of a fleet vessels, data from other vessels can be presented on this monitor (*).
(*) for fleet services, or remote data monitoring, an internet connection is required.
Data is transmitted real-time via satellite communications to the EOS IoT cloud server. By collecting the vessel’s navigation data from DGPS and Gyro compass, the EOS-1000M station is able to calculate the True Wind speed and direction while the vessel is sailing. With the added camera functionality, waves conditions are captured as well.
On board each vessel, two displays were installed. At the officer’s navigation console, a small 7” display shows the vessels own apparent and true wind speed and direction as well as other weather and Navigation data. On a 15” marine touchscreen monitor, crew can see detailed weather data from the other vessel as well as from the shore-based system. Shore personnel can log in to the EOS cloud to see the vessels Weather and Navigation data.
The data is uploaded to the cloud as soon as conditions change. On a moving vessel, data transfers are often once per second. The uploaded data include environmental as well as ship Navigation data. Even with this extensive data transfer, the monthly data transfer is only several 100 Mb. Bandwidth usage on the vessels satellite system is reduced to a bare minimum and can’t be observed during data transfer.
