Orbit2Sp3Format

Writes orbits to SP3 format.

SP3 orbits are usually given in the terrestrial reference frame (TRF), so providing earthRotation automatically rotates the orbits from the celestial reference frame (CRF) to the TRF. Since SP3 orbits often use the center of Earth as a reference, a correction from center of mass to center of Earth can be applied to the orbits by providing gravityfield (e.g. ocean tides).
