More information about the software

PreviSat is an observation software that tracks satellites. It's very simple to use, and it displays the positions artificial satellites in either real-time mode 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 uses a modified version of the SGP4 algorithm (revised in 2006), which uses TLE orbital elements to calculate artificial satellites' geocentric position. PreviSat allows you to view satellites on a map of the world and in a skymap view. You can also calculate all passes of satellites from any place around the world.

PreviSat has the following main features:

  • NORAD SGP4 model (Hoots, Roehrich, 1980; Vallado, 2006)
  • Real-time / Manual mode
  • World map / sky map
  • Visualization of ISS Live and Wall Command Center
  • Topocentric / Equatorial / Terrestrial coordinates (satellites, Sun, Moon)
  • Satellite information, osculating element
  • Weather for NASA bases, observer locations and weather
  • Intuitive interface (handling of TLE, selection of location, options for display)
  • Predictions of orbital events, MetOp flares, SkyMed flares, ISS transits or passes (very fast calculations).
  • Tracking with the Skywatcher mount
  • Satellite data Search (all objects referenced in NORAD since 1957).
  • Available for Windows/Linux/MacOS X platforms
