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

The time remaining until the ships reach that minimum distance. 3. Data Inputs

Uses radio waves to track the relative bearing and range of nearby targets. Ocean CPA method.pdf

More details on reliability in CPA calculations

Recent research, such as that found on ScienceDirect and ResearchGate , suggests improving basic CPA by: Provides GPS-based data including SOG (Speed Over Ground)

Defining a "safe zone" around a ship rather than a single point.

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

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