On m’a partagé ce post LinkedIn pour info, je le pose ici parce qu’il peut y avoir des intérêts pour l’équipe projet IO notamment (mais que seulement).
SATELLITE ORBIT SIMULATOR (SOS) VERSION 24 IS RELEASED!
With this new release, SOS has two new major capabilities: multi-satellite simulations and accurate drag calculations for LEO satellites based on the NRLMSISE-00 air density model.
Although this 3D orbit simulation software for Windows OS was originally developed as an educational tool and companion software for Dr. Motes’ books on space flight, it is also becoming a powerful tool for space mission design; yet is still easy for beginners to use. Although it is not yet certified for operational use, we encourage users to compare its simulation results with other codes.
SOS uses an accurate and fast numerical integrator to solve the 3-body equation of motion for spacecraft near Earth and the Moon. Not only does it include lunar gravity but also Earth bulge, Earth atmosphere, and solar pressure effects. All these effects can be turned off individually for educational purposes.
Earth rotation is accurate based on date and time while Moon and Sun locations relative to Earth are also accurate. As a result, you can view solar eclipses in the past, present, and future from your location on Earth. You can also view the accurate position of major stars and constellations.
To download your free copy, go to https://lnkd.in/gqGtA3vG. The authors, Alan Burgess (UK) and Andy Motes (US), are retired engineers who write this software at home in their free time. Therefore, they do not have a digital signing certificate for the install software. So, be persistent in your attempts to download and install it.
Dr. Motes’ web site is https://lnkd.in/g_PUNKhU. Both web sites have a full description of this software’s capabilities.
