\n<\/h2>\nPreviSat, a satellite tracking program for observation purposes, is available. 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\u00e2\u20ac\u201cSkyMed flares, and calculate ISS transits. 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.<\/p>\n
\n The main features of PreviSat are:\n<\/p>\n\n\n- \n NORAD SGP4 model (Hoots, Roehrich, 1980; Vallado, 2006)\n <\/li>\n
- \n Real-time \/ Manual mode\n <\/li>\n
- \n World map \/ Satellite map\n <\/li>\n
- \n Visualization of ISS Live and Wall Command Center\n <\/li>\n
- \n Topocentric\/Equatorial \/ Terrestrial coordinates\n <\/li>\n
- \n Satellite information, osculating elements\n <\/li>\n
- \n Weather for NASA bases, observer locations and weather\n <\/li>\n
- \n Intuitive interface (handling TLE selections, selecting location, options for display).\n <\/li>\n
- \n Predictions of orbital events, MetOp flares, SkyMed flares, ISS transits or passes (very fast calculations).\n <\/li>\n
- \n Tracking with a Skywatcher mount\n <\/li>\n
- \n Satellite data search (all NORAD objects since 1957)\n <\/li>\n
- \n Available for Windows\/Linux\/MacOS X platforms\n <\/li>\n<\/ul>\n<\/section>\n
