About HELIOS 1A
HELIOS 1A is a satellite from France, launched on Jul 7, 1995 from French Guiana.
It circles Earth every 96 minutes (15.1 times a day), between 540 and 555 km up, on an orbit tilted 98.2° to the equator, so its path covers latitudes up to 82° 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 20 days its lowest point went from 539 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.
