Product Details

ER-FIMU-70 FOG IMU

Introduction:

ER-FIMU-70 FOG IMU is a cost-effective inertial measurement device for navigation, control and dynamic measurement.The system adopts high reliability closed-loop fiber optic gyroscope and accelerometer, and ensures the measurement accuracy through multiple compensation techniques.Strict technology is adopted in the manufacturing process to ensure that the angular motion and linear motion parameters of the carrier can be accurately measured under harsh conditions.

 The product has a good user experience. In addition to wide voltage power supply, users can configure the output bandwidth, data update rate, communication port baud rate and communication protocol according to the use demand.
