About STTW-1

STTW-1 is a satellite from China, launched on Feb 1, 1986 from Xichang Space Center, China.

It sits in geostationary orbit about 35,800 km above the equator near 55°E, turning with Earth so it stays over the same spot.

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