About ORBCOMM FM 36
ORBCOMM FM 36 is a satellite from ORB, launched on Dec 4, 1999 from Air Force Eastern Test Range.
It circles Earth every 100 minutes (14.4 times a day), between 757 and 764 km up, on an orbit tilted 45.0° to the equator, so its path covers latitudes up to 45° 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 24 days its lowest point went from 757 km to 757 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.
