About SDA_1684

SDA_1684 is a satellite from the United States, launched on Oct 15, 2025 from Air Force Western Test Range.

It circles Earth every 104 minutes (13.8 times a day), between 970 and 971 km up, on an orbit tilted 81.3° to the equator, so its path covers latitudes up to 81° 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 11 days its lowest point went from 970 km to 970 km. Sudden rises are engine burns that lift the orbit; slow declines are drag from the thin upper atmosphere.
