About OPS 7613 (P/L 4)

OPS 7613 (P/L 4) is a satellite from the United States, launched on Sep 30, 1969 from Air Force Western Test Range.

It circles Earth every 103 minutes (14.0 times a day), between 891 and 924 km up, on an orbit tilted 70.0° to the equator, so its path covers latitudes up to 70° 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 10 days its lowest point went from 892 km to 891 km. Sudden rises are engine burns that lift the orbit; slow declines are drag from the thin upper atmosphere.
