I am trying to replace an existing system. We used NavChip (InterSense | Precision Motion Tracking Solutions | InterSense Delivers Next-Generation “NavChip” IMU technology) which is no longer in production. I was looking for some IMU similar in performance. I was thinking http://www.analog.com/en/products/sensors/isensor-mems-inertial-measurement-units/adis16488a.html#product-overview will give me a close performance. We mostly rely on the gyroscope and very little on the accelerometer. I am looking on some views and advice on this choice.
