Body-fixed Frame |
| Definitions |
2D angles in body-fixed frame: longitude c1 and latitude c2 + possibly altitude as c3. A planetocentric system with eastward longitudes in the range (0,360)° is required for service interoperability. Current IAU frame is assumed, in particular for definition of the prime meridian. IAU 2009 planetocentric convention applies, in particular eastward longitudes and a north pole located on the north side of the invariant plane of the Solar System for planets and satellites. Parameter c3 is measured above the reference ellipsoid, and can be <0 for interiors. Two other parameters are available to provide other vertical scales if needed (radial_distance and altitude_fromshape). Planetocentric rotating frames are defined as spherical (rather than body). |
