AHRS440CA

The Crossbow AHRS440 is an Attitude & Heading Reference System (AHRS) that utilizes MEMS-based inertial sen- sors to provide an unmatched value in terms of both price and performance. Developed in response to years of extensive application experience in a wide variety of airborne, marine and land applications, the AHRS440 also incorporates many new and enhanced design features including: The AHRS440 provides consistent performance over a wide temperature range in challenging EMI environ-ments across a broad range of input power conditions. It finds uses in a number of different applications including unmanned vehicle control, land vehicle guidance, uncertified avionics and platform stabilization.This high reliability, strapdown inertial system provides attitude and heading measurement with static and dynamic accuracies that exceed traditional spinning mass vertical and directional gyros. Each AHRS440 system comes with a User’s Manual and Crossbow’s NAV-VIEW 2.0 software to assist users with system development, evaluation, and data acquisition.
