Discover how proportional navigation works. Our free online Proportional Navigation Calculator helps engineers and students quickly compute crucial guidance parameters, including missile acceleration command and the impact of the navigation constant, for intercept missions. Simplify complex trajectory calculations and optimize guidance systems with ease.
Formula:
am = N × Vc × ωLOS
- am: Missile Acceleration Command (m/s2)
- N: Navigation Constant (dimensionless, typical range 3-5)
- Vc: Closing Velocity (m/s, relative speed between missile and target along Line of Sight)
- ωLOS: Line-of-Sight (LOS) Rate (rad/s, angular rate of the LOS vector)
