Cartographic Trajectory Parameter Set contains calculations that relate a specified point to the selected central body shape. This parameter set contains the following sub-sets: Cartesian, Centric and Detic. Cartesian includes X, Y, Z and Radius. Centric includes LLR with Latitude, Longitude and Radius, and SubPoint with Cartesian elements. Detic includes several LLA with Latitude, Longitude, Altitude, SurfaceNormal with Cartesian elements without Radius, and SubPoint with Cartesian elements. It also includes Terrain and MSL both with LLA and SubPoint subsets of their own.
