The InertiaCube4 integrates the latest in MEMS inertial technology and utilizes advanced Kalman filtering algorithms to produce a full 360° sourceless orientation tracking sensor.

The 4th generation InertiaCube4 is the industry’s leading 3-Degrees of Freedom (DOF) MEMS-based inertial technology, utilizing advanced Kalman filtering algorithms to produce a full 360° sourceless orientation tracking sensor. The sensor’s portable package with high-end performance and accuracy is ideal for a range of applications, including simulation & training, virtual & augmented reality, motion capture, robotics and human movement analysis.

The InertiaCube4 uses MEMS technology to sense angular rate of rotation, gravity and earth magnetic field along three perpendicular axes. The angular rates are integrated to obtain the orientation (yaw, pitch, and roll) of the sensor. Gravitometer and compass measurements are used to prevent the accumulation of gyroscopic drift through advanced sensor fusion algorithms. This technology offers you several advantages:

  • very low latency
  • unlimited range
  • precise factory calibration
  • smooth, jitter-free tracking
  • in situ static & dynamic magnetic compensation algorithms
