About OPS 7484

OPS 7484 is a satellite from the United States, launched on Jun 10, 1979 from Air Force Eastern Test Range.

It sits in geostationary orbit about 35,800 km above the equator near 154°E, turning with Earth so it stays over the same spot.

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

DSP F8 · These Defense Support System satellites were the space-based segment of a 2-tiered ballistic missile launch detection and warning system.

Orbit height over the past year

Over the last 14 days its lowest point went from 36,171 km to 36,168 km. Sudden rises are engine burns that lift the orbit; slow declines are drag from the thin upper atmosphere.
