The MTi-100 series is the high-performance product range of the MTi product portfolio, with accuracies overpowering conventional MEMS AHRS’s, because of the use of superior gyroscopes and a new optimization filter, going beyond (Extended) Kalman Filter implementations. In addition, the factory calibration is more elaborate to make use of these higher class gyroscopes.
The MTi 100-series can be recognized by the dark-grey base plate and the holes on one side of the casing. These holes are used for the adaptation of the inside air pressure to atmospheric pressure, required for a proper working of the barometer. Note that the electronics inside is protected with a vent that keeps the casing IP67 rated. There are no visual differences between the MTi-100 IMU, MTi-200 VRU and MTi-300 AHRS, other than the label. The MTi-G-700/710 have an extra SMA connector to allow a GPS/GNSS antenna to be attached.
