| Description: There are three basic types of coordinate systems: body-fixed rotating, body-fixed non-rotating, and inertial. A body-fixed coordinate system is one associated with the body (e.g., a planet or satellite). The body-fixed system is centered on the body and rotates with the body (unless it is a non-rotating type), whereas an inertial coordinate system is fixed at some point in space. Currently, the PDS has specifically defined two types of body-fixed rotating coordinate systems: planetocentric and planetographic. However, the set of related data elements are modeled such that definitions for other body-fixed rotating coordinate systems, body-fixed non-rotating and inertial coordinate systems can be added as the need arises. Contact a PDS data engineer for assistance in defining a specific coordinate system. |
