Ocean Cpa Method.pdf -

Recent research, such as that found on ScienceDirect and ResearchGate , suggests improving basic CPA by:

Defining a "safe zone" around a ship rather than a single point. Ocean CPA method.pdf

More details on reliability in CPA calculations Recent research, such as that found on ScienceDirect

The minimum distance (usually in nautical miles) between the vessels at the moment of closest approach. Ocean CPA method.pdf

Provides GPS-based data including SOG (Speed Over Ground) and COG (Course Over Ground). 4. Calculation Methodology

The CPA is traditionally calculated using vector geometry. Determine Relative Velocity ( Vrcap V sub r

): The vector difference between the own ship’s velocity and the target's velocity.
