Description:

PreviSat is a satellite tracking software for observing purposes. Very easy to use, it shows positions of artificial satellites in real-time or manual mode. PreviSat is able to make predictions of their passes, predictions of MetOp and COSMO-SkyMed flares, transits in front of the Moon and Sun, predictions of Starlink satellites passes and several other calculations.

PreviSat implements the SGP4 model (revised in 2006) which uses the GP orbital elements in order to calculate the geocentric position of artificial satellites. PreviSat shows satellites in a world map view or in a sky map view and is able to calculate all passes of satellites for any location in the world.
