Geographical Coverage - Sentinel-1 - Sentinel Online
A single SENTINEL-1 satellite will be able to map the entire world once every 12 days. The two-satellite constellation offers a 6 day exact repeat cycle. The constellation will have a repeat frequency (ascending/descending) of 3 days at the equator, less than 1 day at the Arctic and is expected to provide coverage over Europe, Canada and main shipping routes in 1-3 days, regardless of weather conditions. Radar data will be delivered to Copernicus services within an hour of acquisition.
