About NAVSTAR 15 (USA 42)

It circles Earth every 774 minutes (1.9 times a day), between 21,514 and 21,571 km up, on an orbit tilted 55.1° to the equator, so its path covers latitudes up to 55° north and south.
The map shows where it is right now; the pass list tells you when it next comes over your location.
