Navigation
The navigation subsystem provides state estimation for the missile’s position, velocity, and attitude.
Overview
Navigation systems typically include:
- Inertial Measurement Units (IMU)
- GPS/GNSS receivers
- Sensor fusion algorithms (e.g., Kalman filters)
The navigation system must provide accurate state estimates despite sensor noise and biases.
