Main features:
• Own ship course and speed input
• Target bearing and range observations
• Three-point radar plotting workflow
• CPA and TCPA calculation
• Target course and speed estimation
• Trial maneuver calculation
• Optional trial delay logic
• Relative motion assessment
• Radar-style plotting board

• Built-in Help & User Guide
RadarCop is useful for training, bridge preparation, radar plotting practice, and quick cross-checking of manual calculations.
Important notice:
RadarCop is a calculation aid only. It does not replace official navigation equipment, ARPA, ECDIS, radar, COLREGs, company procedures, or the professional judgment of the Officer of the Watch. All navigational decisions remain the responsibility of the vessel’s bridge team.
