Products
AHRS-8
The AHRS-8 is a fully temperature compensated Attitude Heading Reference System (AHRS), individually calibrated over the -40° to +70° C operating range, providing industry leading heading accuracy in a broad range of challenging application environments. The AHRS-8 provides superior performance by eliminating external magnetic disturbances that affect heading accuracy. It provides 3D absolute magnetic field measurement and full 360° tilt-compensated heading, pitch, and roll data. Our AdaptNav II™ adaptive algorithm provides accurate in-field calibration even in the presence of magnetic distortions due to ferrous objects, and noisy environments within the mounting platform. Sparton’s NorthTek™ Development System enables the world’s only fully programmable navigation sensors, allowing users virtually limitless customizations and applications. The AHRS-8 is fully pin-for-pin compatible with the Sparton DC-4 and GEDC-6 navigation sensors.
