The Sentinel-1 mission comprises a constellation of two polar-orbiting satellites, operating day and night performing C-band synthetic aperture radar (SAR) imaging, enabling them to acquire imagery regardless of the weather. Sentinel-1A and Sentinel-1B share the same orbit plane with a 180° orbital phasing difference. With both satellites operating, the repeat cycle is six days for the Great Lakes.
