Precise Rotational Rate Tracker
This ambitious project is centered on the development of an ultra-precise rotational rate tracker, capable of achieving a remarkable precision level of 0.005 degrees per second. The challenge lies in leveraging off-the-shelf, low-cost inertial measurement units (IMUs) that traditionally offer limited accuracy. By innovatively combining multiple gyroscopes and employing advanced signal processing techniques, this project aims to set a new benchmark in precision rotational tracking.
