IMU30S Strapdown Inertial Measurement Unit

Description
Fogphotonics’s high performance Inertial Measurement Units (IMU) employs the latest FOG and linear acceleration technology. The IMU contains three FOG sensors and three accelerometer sensors, including the support electronics and algorithms.The IMUs provides fully compensated measurements of angular rates and linear accelerations suitable for navigation, stabilization, and flight control. The IMUs are manufactured in several form factors using the same inertial sensors, electronic design, and basic parts making the IMU cost and size competitive. Our IMUs are ideal candidates for any demanding applications.Our IMUs are intended for use in a multitude of applications. The units deliver fully-compensated angular rates and linear accelerations. The sensors are classified and categorized according to their Bias instability, Noise performance and dynamic ranges.
