More information about the software

PreviSat is an observation software that tracks satellites. It is easy to use and shows the position of artificial satellites either in real time or manually. PreviSat can make predictions about their passes, predict MetOp flares and COSMO–SkyMed flares, and calculate ISS transits. 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 is able calculate all satellite passes for any location anywhere in the world, and shows satellites both in a globe view and a sky view.

The main features of PreviSat are:

  • NORAD SGP4 model (Hoots, Roehrich, 1980; Vallado, 2006)
  • Real time / Manual mode
  • World map/Sky map
  • Visualizations of ISS Live and Wall Command Center
  • Topocentric/Equatorial / Terrestrial coordinates
  • Satellite Information, Osculating Elements
  • Weather for observer location and NASA bases
  • 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 a Skywatcher mount
  • Satellite data Search (all objects referenced in NORAD since 1957).
