About SENTINEL 1A

SENTINEL 1A is a satellite from the European Space Agency, launched on Apr 3, 2014 from French Guiana.

It circles Earth every 99 minutes (14.6 times a day), between 693 and 695 km up, on an orbit tilted 98.2° to the equator, so its path covers latitudes up to 82° north and south.

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