Meggitt’s Inertial Measurement Units (IMU) provide high performance, dynamic angular velocity and acceleration measurements across three orthogonal axes.
Compact and robust, they are designed for extreme environments. Their design combines the use of three MEMS-based accelerometers and three vibrating structure gyrometers, positioned on each of axis. The use of MEMS technology ensures high reliability and robustness within many applications and environments. The integration of Meggitt’s own digital electronics increases the IMU’s overall accuracy.
Individual sensor output is corrected for non-linearity, temperature drift and miss-alignment errors. Acceleration, angular speed and temperature outputs are available as differential analog and RS 485 Modbus RTU outputs. Bandwidth may be user-modified through the Modbus, which also has built-in monitoring and self-test functions on each axis.
2-axis attitude sensors are going to be available mid-year and AHRS in 2016.
