About IRS 1D
IRS 1D is a satellite from India, launched on Sep 29, 1997 from Sirharikota.
It circles Earth every 100 minutes (14.4 times a day), between 736 and 810 km up, on an orbit tilted 98.9° to the equator, so its path covers latitudes up to 81° north and south.
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 22 days its lowest point went from 737 km to 736 km. Sudden rises are engine burns that lift the orbit; slow declines are drag from the thin upper atmosphere.
From Space-Track element sets, one point a day.
