From Orbit to Bridge: The Latency Budget of Near Real-Time Arctic Ice Maps
Is your Arctic ice chart already obsolete? We break down the ‘Latency Budget’ of Near Real-Time (NRT) mapping—from Sentinel-1 orbit files to the 10-minute target of future AI pipelines. In the Arctic, time isn’t just money—it is structural integrity. When a vessel is navigating the Northern Sea Route or the Northwest Passage, an ice chart…

Can Satellites Really Measure Sea Ice Thickness? CryoSat-2 vs. Operational Reality
Can satellites really measure sea ice thickness for ship routing? We analyze CryoSat-2 accuracy, the physics of altimetry, and why latency makes it dangerous for navigation. The characterization of sea ice thickness (SIT) is the “Holy Grail” of the polar climate system. It dictates the mass balance of the Arctic and serves as the primary…
