About ACS 3
ACS 3 is a satellite from the United States, launched on Apr 23, 2024 from Rocket Lab Launch Complex.
It circles Earth every 103 minutes (14.0 times a day), between 848 and 946 km up, on an orbit tilted 97.3° to the equator, so its path covers latitudes up to 83° 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 16 days its lowest point went from 866 km to 848 km. Sudden rises are engine burns that lift the orbit; slow declines are drag from the thin upper atmosphere.
From Space-Track element sets, one point a day.
