I'm trying to add support for SPICE ephemerides to Orbiter.
First results here: [ame="http://www.orbithangar.com/searchid.php?ID=3329"]SPICE ephemeris module[/ame]
SPICE is NASA's library for archiving data for space missions - spacecrafts, planets, satellites positions, orientations, and other data. In Orbiter it may be useful for computing high-precision positions and velosity of planets/moons.
Small examples (adding Pluto/Charon into Orbiter using this addon):
pluto.cfg
charon.cfg
