About ESSA 7 (TOS-E)

ESSA 7 (TOS-E) is a satellite from the United States, launched on Aug 16, 1968 from Air Force Western Test Range.

It circles Earth every 115 minutes (12.5 times a day), between 1,431 and 1,473 km up, on an orbit tilted 101.6° to the equator, so its path covers latitudes up to 78° north and south.

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