On December 5th, 2000, ImageSat international became the first, non-US-based company to successfully deploy a commercial, high-resolution, imaging satellite. This was EROS A, weighing in at 250 kg, which was propelled into its orbital slot by a Russian Start-1 launch vehicle.
The EROS A possesses a camera with a focal plane of Charge Coupled Device (CCD) detectors to produce a standard image resolution of 1.9 meters and sub-meter resolution using hypersampling techniques. The swath is 14 km at Nadir (perpendicular to the Earths surface). The satellite orbits at an altitude of ~500 km, with data transmission at 70 Mbit/s.
The EROS B is slightly larger in size to the EROS A, but quite similar in appearance. Updated capabilities include the use of a larger camera of the CCD/TDi genre (Charge Coupled Device/Time Delay Integration). A standard panchromatic resolution of 0.70m at an altitude of about 500 km is offered. Plus, the EROS B has a larger on-board recorder as well as improved pointing accuracy and a faster data communication link.
