Guided Rocket Navigation design and implementation on Hardware in Loop Simulation

The main role of Rocket Navigation System is to deliver an attitude command to Flight Control System hence the rocket can be directed to a particular path or a specific target. This command is produced from Trajectory Planning algorithm. The Navigation System also performs attitude estimation by using the Extended Kalman Filter. The inputs of Navigation System are obtained from GPS, IMU, Pitot tube, Altitude meter and actuator encoder which have been modeled in SIMULINK. From the test results, the Trajectory Planning algorithm is successful enough to give an attitude command and the rocket can reach the target. Also, the Extended Kalman Filter has successfully estimated pitch angle, u-velocity, and w-velocity. Moreover, the Extended Kalman Filter has successfully filtered out the pitch rate noise from the simulated IMU sensor.
