TELEOS 1 is a 400-kilogram (880-pound) commercial Earth imaging observatory made by ST Electronics in Singapore. TeLEOS 1 has a five-year design life, and its unique orbit taking the satellite 15 degrees north and south of the equator will yield regular revisits of observation targets every 12 to 16 hours. With a sharp-eyed camera capable of resolving objects on the ground as small as a meter, or 3 feet, TeLEOS 1 complements Earth observation satellites in more traditional sun-synchronous orbits.
