About SEDSAT 1
SEDSAT 1 is a satellite from the United States, launched on Oct 24, 1998 from Air Force Eastern Test Range.
It circles Earth every 100 minutes (14.3 times a day), between 540 and 1,021 km up, on an orbit tilted 31.4° to the equator, so its path covers latitudes up to 31° 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 23 days its lowest point went from 540 km to 540 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.
