About BD-17
BD-17 is a satellite from China, launched on Mar 30, 2015 from Xichang Space Center, China.
It sits in geostationary orbit about 35,800 km above the equator near 108°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.

Orbit height over the past year
Over the last 26 days its lowest point went from 35,620 km to 35,625 km. Sudden rises are engine burns that lift the orbit; slow declines are drag from the thin upper atmosphere.
