About SECOR 1B
SECOR 1B is a satellite from the United States, launched on Jan 11, 1964 from Air Force Western Test Range.
It circles Earth every 103 minutes (14.0 times a day), between 898 and 923 km up, on an orbit tilted 69.9° to the equator, so its path covers latitudes up to 70° north and south.
The map shows where it is right now; the pass list tells you when it next comes over your location.
