One of the required technological bricks for the development of guided ammunitions is the navigation system. Classical algorithms based on the integration of signals sensed by an inertial measurement unit (IMU) leads to a continuously increasing drift due to the performance of the sensors, the possible saturations and uncertain initial conditions.
One possible solution to estimate the position and the attitude of the projectile is to rely on radio-frequency waves. Therefore, we proposed to develop a navigation system, complementary to the IMU, based on analog integrated micro-wave sensors and a dedicated antenna array.
The objective of this PhD is to design these micro-wave sensors in BiCMOS technology and to study their integration in a navigation system for munitions applications.
