 Proportional navigation

Proportional navigation is a guidance strategy used primarily in missile and pursuit vehicle control systems. The primary aim of proportional navigation is to enable a missile or aircraft to intercept a moving target effectively. The fundamental principle of proportional navigation is based on maintaining a constant line of sight to the target while adjusting the interceptor's trajectory. The key aspects of this method include: 1. **Line of Sight (LOS) Rate**: This refers to the angle rate at which the interceptor is closing in on the target.
