Go to the 'Settings' menu and select whether you want to use your device's Location Services or an external GNSS sensor to display your user position. There are two ways to display your current position using an external sensor:
1. Use an external 'GNSS Dongle' (see picture), which is a plug in sensor for your computer and costs approx. 15 EUR (we usually use: 'G-MOUSE' from 'DIY Mall'). Connect the sensor via USB and click on the 'User Position' button in the top left corner in IcySea. You will be asked which COM Port sensor you want to use and after selecting the correct one the sensor will connect and IcySea will display your position. This method is applicable for all operating systems (Windows, Linux, macOS).

2. Connect IcySea to your ship's GNSS via a virtual serial port:
i) Install the freely-available software HW VSP3 (Windows only) on the IcySea computer (admin rights are required). The software creates a virtual serial port.
ii) Input the IP address of the server distributing the GNSS position on the ship into the HW VSP3 software and select the corresponding COM port (see image).

iii) Go to the IcySea 'Settings' menu (wheel symbol in the top left corner), navigate to the 'User Position' menu and select 'Connect to GNSS sensor via serial port'. Also select the correct baud rate, which is adjustable within the HW VSP3 settings.
iv) Close the IcySea 'Settings' menu and click on the 'User Position' button in the top left corner. IcySea will connect and move the screen to your current position.

All data products are gathered from external sources. As soon as the respective data set becomes publicly available it is processed and displayed in IcySea, which allows you to utilize near real-time information for your operations.
Sea-ice concentration
Activate the layer and a legend at the bottom left gives additional information including a timestamp. The sea-ice concentration layer is updated up to eight times a day, so you should refresh the layer regularly.
Surface temperature
Click on the layer name in the layer control panel at the top right hand corner of the app to activate the layer. You will now see surface temperature timestamp and colour map information in the bottom left hand corner of the page. Surface temperature information is updated daily at approximately 14:00 UTC.
Ice drift forecast
Activate the layer and a legend at the bottom left gives additional information including when the forecast was calculated. The ice drift forecasts are updated once per day.
Ice charts
Activate the ice charts layer and the corresponding legend in the bottom left corner will provide the date and timestamp. When clicking on the ice chart polygons of the DMI ice charts the egg code box will also display the age information. Data updates depend on where the data is coming from. DMI updates usually come in between every one to three days, while US ice charts are produced on a weekly basis.
Radar and optical images
On the layer button of radar/optical images click on the "clock" symbol. All images will be colour-coded according to age, legend appears at the bottom left. If you zoom in the tiles of interest, their exact age of data tiles will show. See the example below:

IcySea is always global, covering both polar regions. By default IcySea shows the Arctic; to show the Antarctic first click on the settings wheel in the upper left corner of the window to open the "Settings" dialog box. Then click on "Show antarctic" option from within the "Polar regions" section and then close the dialog box by clicking on the X in the top right-hand corner. You should now see the Antarctic displayed in IcySea.
