About ISO
ISO is a satellite from the European Space Agency, launched on Nov 17, 1995 from French Guiana.
It circles Earth every 1,409 minutes (1.0 times a day), between 659 and 69,847 km up, on an orbit tilted 0.5° to the equator, so its path covers latitudes up to 1° north and south.
The map shows where it is right now; the pass list tells you when it next comes over your location.
