About NOAA 18
NOAA 18 is a satellite from the United States, launched on May 20, 2005 from Air Force Western Test Range.
It circles Earth every 102 minutes (14.1 times a day), between 836 and 857 km up, on an orbit tilted 98.8° 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 366 days its lowest point went from 836 km to 836 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.
