Navigation Support System for Rotating Missiles

The key problem in the navigation of rotating missiles based on inertial navigation using MEMS sensors is the problem of precisely calculating the rotational speed. Limitations in the accuracy of rotational speed measurement are the main cause of errors in inertial navigation. This problem constitutes a significant barrier to the improvement and control of traditional, unguided rotating missile designs. As a potential solution, an innovative system supporting rotational speed calculation is proposed, which would measure changes in the missiles surroundings. The work presents the issue of developing a system supporting the precise calculation of the rotational speed of a rotating missile. The issues related to the use of inertial navigation systems based on MEMS sensors and the problems resulting from the use of this type of sensors in rocket technology are presented in detail. A dedicated research stand is presented along with the results of preliminary laboratory tests, which indicate the possibility of obtaining data on the missiles inclination angle by analyzing the light intensity in its surroundings.
