Two generic classes of Proportional Navigation (PN) laws exist depending on whether the control acceleration of the pursuer is referenced relative to the pursuer velocity vector or the target-pursuer line-of-sight (LOS). This paper makes a critical comparison of the two types of laws, covering aspects of their implementation, analysis and trajectory behavior. It is shown that the LOS-referenced PN laws possess serious limitations in terms of implementation and trajectory behavior. These include forward acceleration and braking as a part of the control effort, relative inefficiency in terms of control effort requirements, restrictive launch conditions and singularities in acceleration requirements.
