Inertial Sensor Calibration

Inertial Sensor Extended 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-210 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-210 (-40°C to +85°C).
