The Inertial Labs RMCU utilizes 3-axes, each precision MEMS accelerometer, miniature Fluxgate magnetometers, and MEMS gyroscopes to provide accurate Heading, Pitch, and Roll of the device under the measure. Integration of gyroscopes’ output provides high-frequency, real-time measurement of the device rotation about all three rotational axes. Accelerometers and Fluxgate magnetometers easure absolute, very accurately in static and dynamic conditions Pitch, Roll, and Heading/Azimuth at RMCU initial alignment and provide ongoing corrections to gyroscopes during operation.
