Position Dependent Systems

For the study of the local plasma environment of a spacecraft it is common to choose an axis system which depends on the position of the spacecraft. Widely used are Radial-Tangential-Normal systems defined by the radial vector from a central body to the spacecraft and the magnetic or rotational normal axis of that body. For highest precision one should use reference systems at the epoch of date.
