Enclosed in a precision anodized aluminum enclosure, the VN-110 offers additional protection of the internal MEMs sensors and electronics. The use of precision CNC milled aluminum parts ensures that the axis alignment provided by our factory calibration process is maintained during installation in its final configuration. Interfacing with the module is made through circular push-pull 10-pin connectors.
Tactical-Grade MEMS IMU
Utilizing the latest advancements in Microelectromechanical systems (MEMS) technology, the VN-110 incorporates an suite of tactical-grade inertial sensors, including a 3-axis accelerometer, 3-axis gyroscope and 3-axis magnetometer. The VN-110 has been designed to achieve the highest performance possible by filtering out common error sources, such as sensitivity to supply voltage variations and temperature dependent hysteresis.
- < 1 °/hr in-run gyro stability
- < 10 µg in-run accel bias stability
- Ultra low noise accel and gyro (0.04 mg/√Hz and 3.24 °/hr / √Hz)
- High accel and gyro ranges (±15 g and ±490 °/s)
Extended Inertial Sensor Thermal Calibration
MEMS inertial sensors are subject to several common sources of error: bias, scale factor, misalignments, temperature dependencies, and gyro g-sensitivity. To ensure the highest level of accuracy, each VN-110 sensor undergoes a rigorous calibration process to minimize these error sources. Compensation parameters calculated during these calibrations are stored on each individual sensor and digitally applied to the real-time measurements. This calibration process is performed over the full thermal operating range of the VN-110 (-40°C to +85°C).
