Smart-MEMS based inertial measurement units: gyro-free approach to improve the grade
Résumé
Inertial measurement units (IMU) are essentially a combination of acceleration and rotation rate sensors, generating position and attitude information. For tactical and strategic applications, traditional macro-scale technologies are currently employed, owing to their very high accuracies and low drift. But they are very bulky and power consuming. Recent advancements in micro-electro-mechanical-systems (MEMS) technology together with smart data fusion techniques have enabled us to explore MEMS based IMUs, which is the subject of this paper.
