A Columbus Polar Platform scenario for Earth observations is outlined. It features: 2 platforms in coordinated Sun-synchronous orbits at an altitude of 800 km: 1 in a morning orbit, with a descending node between 09.30 and 10.30, and the other in an afternoon orbit, with an ascending node between 13.00 and 14.30; a multidisciplinary payload divided between the platforms with 2.4 tons per platform and the capability for further growth; and servicing every 3 yr for maintaining the capabilities, adding new payloads, and upgrading payloads. Data rates up to several hundred megabits/sec are compatible with: direct downlinking, and the proposed European Data Relay Satellite System. Lower data rates generated globally are compatible with on-board recording techniques. The methods for acquiring the data on the ground are compatible with the delivery time requirements for the different applications.
