Inertial measurement units (IMUs) with 10-degree-of-freedom (DoF) measurements provide greater accuracy for orientation sensing in platform stabilization, navigation and instrumentation applications. However, in addition to a tri-axis gyroscope, tri-axis accelerometer, tri-axis magnetometer and a pressure sensor, the sensor must also have a sensor fusion algorithm to combine the readings from each device. With its ADIS16480, Analog Devices provides the user all of these elements with the fusion algorithm implemented by Analog Devices’ ADSP-BF512 Blackfin processor – all housed in a single package.
The algorithm uses an extended Kalman filter (EKF) to fuses the sensor inputs over time and deliver precise positioning as well as reduced design time and cost.
