Inertial Aerosystems is introducing new versions of two of its established high-tech products, both of which benefit from enhanced performance. Manufactured by Netherlands-based Xsens, the MEMS-based MTi and MTi-G are miniature gyro-operated attitude and heading reference systems (AHRS). The enhancements are derived from a new sensor fusion algorithm and hardware improvements.
+++ STOP PRESS 2 November 2011 - These products are no longer available from ETLG Inertial Aerosystems, but contact the company for information about its other attitude and heading reference systems. +++
The MTi model provides drift-free 3D orientation, as well as calibrated 3D acceleration, rate of turn and magnetic heading at a 100Hz data rate. Enhancements include improved heading performance, especially within a magnetically disturbed environment, and better data integrity during periodic accelerations and very slow rotations. Also included are new gyroscopes with 50 per cent lower signal noise and an option for an 18g accelerometer range.
With all the performance of the MTi, the MTI-G model also includes an integrated GPS, static pressure sensor and Kalman filtering. Position, velocity and altitude are provided in addition to all the features of the MTi. Enhancements include improved use of the GPS signal, which results in better orientation performance, plus all of the MTi improvements.
Weighing approximately 68g and measuring 58 x 58 x 33mm (MTi-G), the units are suitable for use where space and weight are at a premium, and can operate in tough environments within a temperature range of -20 to +55degC.
Typical applications will be found in the robotics, aerospace, automotive and marine industries, as well as in pedestrian navigation and virtual reality.
