Abstract: Angular acceleration sensors technologies are evolving and emerging in various applications. In this paper, we propose an angular accelerometer-based inertial navigation system. One application of such systems can be highly maneuvering platforms where direct measurement of angular acceleration is desired. To that end, a review of modern angular acceleration sensor technologies and their possible applications is provided. Two angular acceleration-based inertial navigation system architectures are suggested, and their equations of motion are derived. Additionally, an analytical assessment for short time periods of pure inertial navigation is provided with a comparison to traditional and gyro-free inertial navigation architectures.
