ISS Orbit Tracker

LIVE SGP4

Real-time international space station orbital kinematics, ground track telemetry, and city flyover predictor.

Orbital Physics Manual

1. Low Earth Orbit (LEO) Velocity:

The ISS circles Earth every 92.68 minutes at $v = \sqrt{GM / (R_E + h)} \approx 7.66\text{ km/s}$ (~27,600 km/h) experiencing 16 sunrises/sunsets every 24 hours.

2. Orbital Inclination (51.6°):

Chosen to enable launches from both Baikonur Cosmodrome (Kazakhstan) and Kennedy Space Center (Florida), covering 90% of Earth's populated surface.
