About the software

PreviSat is a satellite tracking software for observing purposes. Very easy to use, it shows the 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, ISS transits and several other calculations.
PreviSat implements the SGP4 model (revised in 2006) which uses the TLE 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.

The main features of PreviSat are:

  • NORAD SGP4 model (Hoots, Roehrich, 1980; Vallado, 2006)
  • Real time / Manual mode
  • World map / Sky map
  • ISS Live and Wall Command Center visualization
  • Topocentric / Equatorial / Terrestrial coordinates (satellites, Sun, Moon)
  • Osculating elements, satellite informations
  • Weather for observer location and NASA bases
  • Intuitive interface (handling of TLE, selection of location, options for display)
  • Prediction of passes, MetOp and SkyMed flares, ISS transits and orbital events (very fast calculations)
  • Tracking with a Skywatcher mount
  • Satellite data search (all objects referenced by NORAD since 1957)
  • Available for Windows/Linux/MacOS X platforms
