Fully automated support of ice breaker activities with near-real time radar images from space

Ice breakers traversing ice infested waters save fuel and time by choosing the most trafficable route. Finding such routes is a difficult task which needs years of experience and a technique to observe the continuously changing ice conditions ahead. If available, helicopter flights are a suitable but expensive surveying tool. The ice situation closer by can be surveyed with a ship-based ice radar. However, to get an overall impression of the ice situation along the planned route, satellite images are inevitable.

The two Sentinel-1 satellites from the European Space Agency (ESA) take radar images of ice covered oceans in the Arctic and Antarctic several times a day. These images are independent of weather and light conditions. Sentinel-1 data are open data and therefore available free of charge.

Nevertheless, it is a considerable effort to ensure that the most recent Sentinel-1 radar images around a ship’s position are available on board. And this as fast as possible to account for continuously changing ice conditions. Drift+Noise Polar Services offers fully automated and customized Sentinel-1 images of the ice situation around your ship, available in sizes transferable via an Iridium satellite connection, several times a day and less than three hours after satellite recording. The most recent cruise of the research ice breaker Polarstern is being supported in this manner (see figure above).
