About CAT 3
CAT 3 is a satellite from the European Space Agency, launched on Jun 19, 1981 from French Guiana.
It circles Earth every 317 minutes (4.5 times a day), between 218 and 17,849 km up, on an orbit tilted 10.2° to the equator, so its path covers latitudes up to 10° north and south.
The map shows where it is right now; the pass list tells you when it next comes over your location.
