For higher orbits, you can update your TLE every few weeks. For low orbiting objects (altitude less than 500 km) TLE data should be updated every few days. To keep tracking software working precisely, one should update elements periodically. Orbitron uses these TLE files to track satellite positions. Orbital data for each object is grouped, and distributed as a Two Line Element (TLE) file. Known orbital parameters like inclination, eccentricity, argument of perigee, mean motion (revolutions per day), etc. Calculations are done based on known orbit parameters determined at epoch. It has a large database of cities around the world so that you can find the precise time and location of any satellites over any place.ĭue to predictable conditions of satellite movement in space (lack of atmosphere) computer software can calculate a satellite’s position for given moment. It tracks the path of even the sun and the moon. At present it can track 20,000 satellites and all of them can be tracked at the same time. It’s probably one of the easiest and most powerful satellite trackers, according to opinions of thousands of users from all over the world. Orbitron shows the positions of any satellites at any given moment in real or simulated time. This software is more than 10 years old and has been used by weather professionals, satellite communication users, astronomers, UFO hobbyist and even astrologers.

Orbitron is a satellite tracking system for radio amateur and observing purposes. Did you ever wanted to know which satellites are over your head at the precise moment? Did you ever wonder where the International Space Station could be right now? Do you want to catch a glimpse of it in the night sky? The answers to all these questions can be found in this wonderful tool called Orbitron.
