What's more, you can get comprehensive information about the satellite numerical position in different frames (terrestrial, horizontal, equatorial), several characteristics, such as velocity and magnitude, position of the Sun and Moon, Cartesian position of the satellite and osculation elements, apogee and perigee, orbital period, as well as info about the brightness and dimensions of the satellite.

PreviSat offers support for two built-in modes when it comes to observing the displacement of the satellites in real time or manually setting the time for displaying satellite positions. There are also several built-in parameters that help you gather important information about the position of a satellite in different frames, osculating elements (Keplerian orbital elements), TLE (two-line element) set for computing the position of a satellite at a particular time, predictions, Iridium flares, as well as other handy configuration settings. It features a clean feature lineup where you can view the satellites on a world or sky map. The tool is able to offer predictions about satellites' passes and Iridium flares. PreviSat is a satellite tracking software whose purpose is to help you monitor and observe the position of artificial satellites in real time.
