![]() ![]() Also, thanks go to Pavel Atnashev for important ideas on adapting the discovery for use by GIMPS. Many thanks to Mihai Preda for discovering the paper on the breakthrough and realizing its importance to the GIMPS project. Should you run into any problems, support is available at this thread at Mersenne Forum. While not a required upgrade, at some point in the future only users running version 30.3 with PRP proofs will be assigned first-time primality tests. ![]() Version 30.3 is now available with PRP proofs. ![]() This breakthrough will nearly double GIMPS' throughput in the long run. Great Internet Mersenne Prime Search (GIMPS)ĭonate your computer's processing power to help search for prime numbers.īIG Changes Are Here! Prime95 version 30.3 released.įor almost 25 years, GIMPS has looked for new Mersenne primes by running a primality test on one computer and later running the exact same primality test on another computer to guard against hardware errors having corrupted the first primality test.Ī breakthrough by Krzysztof Pietrzak makes it possible to eliminate the second primality test! The first primality test produces a proof file that can be securely verified with less than 0.5% of the work required to re-run the primality test. Use Wine on macOS and the Windows version.)Ĭlick here to visit the author's website. This download is for the Windows version. Satellite data search (all objects referenced by NORAD since 1957)Īvailable for Windows/Linux/MacOS X platforms Prediction of passes, MetOp and SkyMed flares, ISS transits and orbital events (very fast calculations) ![]() Intuitive interface (handling of TLE, selection of location, options for display) Weather for observer location and NASA bases Osculating elements, satellite informations Topocentric / Equatorial / Terrestrial coordinates (satellites, Sun, Moon) ISS Live and Wall Command Center visualization NORAD SGP4 model (Hoots, Roehrich, 1980 Vallado, 2006) PreviSat is able to make predictions of their passes, predictions of MetOp and COSMO-SkyMed flares, ISS transits and several other calculations. Very easy to use, it shows positions of artificial satellites in real-time or manual mode. PreviSat is a satellite tracking software for observing purposes. Free, open source satellite tracking software. ![]()
