About IRS 1A

IRS 1A is a satellite from India, launched on Mar 17, 1988 from Tyuratam Missile and Space Complex.

It circles Earth every 103 minutes (14.0 times a day), between 893 and 914 km up, on an orbit tilted 98.8° 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.
