Inertial Sensors

Distortions, whether from magnetic and ferrous materials or electric current, can spell disaster for the standard sensor.

Sparton sensors, however, incorporate our proprietary AdaptNav™ solution and, in some models, gyro-enhancement to provide pinpoint heading accuracy. For us, no environment is too harsh and no terrain too unforgiving.

Considered one of the industry’s best performing inertial systems, the Sparton AHRS uses MEMS magnetometer, accelerometer and gyroscope technology. This provides seamless heading and position information even in areas where GPS signals are unavailable and GPS-based devices are unable to operate.

Key Features

Enhanced 3D Adaptive Calibration improves calibration speed and stability, while compensating for errors caused by positional changes in dynamic environments.

360º Rollover Capability maintains absolute accuracy regardless of angle, even when completely inverted.

3D Acceleration determines acceleration in three dimensions simultaneously.

Adaptive Pitch and Roll Calculation provides three dimensional absolute magnetic field measurement and full 360º tilt-compensated bearing, pitch, and roll with 3-axis, tilt-compensated sensors.

Gyro Enhancement provides additional inertial system heading accuracy in the presence of stray magnetic fields.

High Resolution Magnetics permit finer discernment of the Earth’s magnetic field, thereby improving our sensor’s level of accuracy in dynamic or challenging conditions.

True North Computation uses NOAA magnetic declination tables corrects for an application’s present location, thereby providing a “true north” heading.

Sleep Mode allows our sensors to use less energy, which increases battery life.
