Detailed Description

Satellite Radial Coordinate System.

The fundamental plane is the satellite's orbit, and the origin is at the center of the Earth. The P axis points towards perigee, and the Q axis is $90^{\circ}$ from the P axis in the direction of satellite motion. The W axis is then normal to the orbit. The PQW system always maintains an orientation towards perigee and is therefore best suited for robits with a well-defined eccentricity. (Vallado, pg 41)
