Radar Plotting brings professional marine radar-plotting tools to your mobile device. Designed for navigators, the app calculates CPA/TCPA and other kinematic data, suggests evasive and rescue manoeuvres, detects current, and visualises results on an interactive radar sheet.
Key features:
- CPA & TCPA calculation from 2–3 radar fixes or manual speed input (true & relative motion)
- Evasive manoeuvres: turn starboard/port and speed reduction with COLREG conformity guidance (R13/R14/R15)
- Double-target strategies: compute safe manoeuvres against two simultaneous contacts
- Rescue & escape planning: optimal interception and escape routes (including scenarios with faster pursuers)
- Current/drift detection from successive observations
- Interactive radar sheet with adjustable distance and speed scales, selectable TRUE/RELATIVE motion and animated playback
- Import/export scenarios via QR code; save and share session reports (PDF)
- Available in English and Italian; works offline and on Android/iOS (Ionic + Capacitor)
Important: Radar Plotting is a decision-support and training tool. It does not replace certified navigational instruments, professional judgement or watchkeeping procedures. Always comply with COLREG and your company/local regulations.
