SDO is in a 28 degree inclined geosynchronous orbit, 36,000 km above Earth's surface. Unlike a satellite in geostationary orbit, which appears to just hover above Earth, SDO actually traces a figure-8 in the sky every day to have a direct line of sight to White Sands, New Mexico, where the two dedicated ground stations are located.
