AHRS-8 MEMS-based Inertial Sensor

Sparton Corporation presents AHRS-8, a highly advanced inertial sensor that enhances a best-in-class product line. The AHRS-8 is a MEMS-based (micro electro-mechanical systems) attitude heading reference system. Fully temperature compensated and individually calibrated over temperature, the AHRS-8 is the perfect navigation solution for challenging environments requiring the highest level of accuracy, such as in oil and gas exploration. AHRS-8 complements Sparton’s full line of inertial sensor solutions designed specifically to meet systems designer’s stringent requirements.

“Our AHRS-8 provides full in-sensor programmability via the NorthTek™ Development System and offers superior accuracy and stability at temperature extremes with our revolutionary AdaptNav II™ sensor fusion algorithm,” said Jim Lackemacher, Vice President of Sparton Navigation & Exploration and Defense and Security divisions. “The AHRS-8 also provides revolutionary centripetal acceleration error correction that drives the highest level of accuracy in the most dynamic situations,” he added.

Features of AHRS-8 :

• AdaptNav II. adaptive algorithms provide real-time optimization of navigation sensor performance in varying electro-magnetic and dynamic operating environments
• Fully temperature compensated and individually calibrated over the -40. to +70. operating range, providing industry leading heading accuracy in a broad range of application environments
• Powerful user sensor customization via the NorthTek. Development System
• Revolutionary centripetal acceleration error correction algorithm provides superior roll orientation stability in highly dynamic environments
• User selectable accelerometer dynamic ranges
• Low power, with power management capability (sleep mode)
• True North heading output via built-in World Magnetic Model
• Robust, fully encapsulated design
