Description
Calculate target kinematic data including CPA and TCPA. Determine evasive maneuvers for single and multiple targets. Assess current and escape maneuvers. Evaluate rescue and speed reduction options.
Radar Plotting provides advanced radar-plotting capabilities for iPhone and iPad. Compute CPA/TCPA, estimate true motion, plan evasive/rescue/escape manoeuvres, and analyse two-target encounters — all visualised on an interactive radar sheet.
Highlights:
- Precise kinematic calculations (CPA/TCPA, aspect, true & relative speed)
- Evasive manoeuvres with COLREG guidance
- Rescue & escape planning, including scenarios with faster vessels
- Double-target handling
- Current/drift estimation
- Interactive canvas with adjustable scales and animated trajectory playback
- Import/export via QR code and PDF report generation
