Polar orbit; Sun-synchronous - designed for long term repeatability of data, Typically nadir viewing, crosses every point on Earth ~ 12-14 days near local solar noon/local midnight, Landsat series collecting data since 1972, Pointing capability, satellite constellations. Inclined Equatorial Orbit: ISS; Sun-asynchronous - similar illumination 3-4 days every 90 days, Nadir to highly oblique imagery possible from hand-held cameras, WORF, external sensors, Provides opportunity to collect unique datasets for scientific study, disaster response, Data is complementary to polar-orbiting satellite data.
