About OAO 1

OAO 1 is a satellite from the United States, launched on Apr 8, 1966 from Air Force Eastern Test Range.

It circles Earth every 100 minutes (14.3 times a day), between 771 and 781 km up, on an orbit tilted 35.0° to the equator, so its path covers latitudes up to 35° north and south.

The map shows where it is right now; the pass list tells you when it next comes over your location.

Orbit height over the past year

Over the last 9 days its lowest point went from 772 km to 771 km. Sudden rises are engine burns that lift the orbit; slow declines are drag from the thin upper atmosphere.
