About ISS (UNITY)

ISS (UNITY) is a satellite from the United States, launched on Dec 4, 1998 from Air Force Eastern Test Range.

It circles Earth every 93 minutes (15.5 times a day), between 414 and 424 km up, on an orbit tilted 51.6° to the equator, so its path covers latitudes up to 52° north and south.

The map shows where it is right now; the pass list tells you when it next comes over your location.
