Application shows the positions of satellites at any given moment (in real or simulated time).
It's FREE (Cardware) and it's probably one of the easiest and most powerful satellite trackers, according to opinions of thousands of users from all over the world.
8, 2013 Landsat 8 officially began normal operations on May 30, 2013, when the leadership for satellite operations transferred from NASA to the U. The USGS now manages the satellite flight operations team within the Mission Operations Center, which remains located at NASA’s Goddard Space Flight Center in Greenbelt, Md.
It was named Sputnik 1, and spent 92 days in Earth orbit.
Since then man has launched thousands of rockets, and put thousands of satellites in orbit.
Calculations are done based on known orbit parameters determined at epoch.
Known orbital parameters like inclination, eccentricity, argument of perigee, mean motion (revolutions per day), let us track satellite for a reasonable period of time after epoch.
