About NAVSTAR 19 (USA 54)
NAVSTAR 19 (USA 54) is a satellite from the United States, launched on Mar 26, 1990 from Air Force Eastern Test Range.
It circles Earth every 754 minutes (1.9 times a day), between 20,930 and 21,186 km up, on an orbit tilted 53.4° to the equator, so its path covers latitudes up to 53° north and south.
The map shows where it is right now; the pass list tells you when it next comes over your location.
