MOOG Crossbow NAV440 heading, attitude and positioning sensor
|Within Vocab||SeaVoX Device Catalogue|
|Alternative Labels||Moog NAV 440|
|Definition||A combined navigation, velocity and orientation system. It is used in applications such as unmanned vehicle control. It measures position, dynamic velocity, and dynamic roll, pitch and heading. It comprises a 6-DOF (Degrees of Freedom) MEMS inertial sensor cluster that includes three axes of MEMS angular rate sensing and three axes of MEMS linear acceleration sensing. These sensors are based on silicon bulk micromachining technology. It also includes a 3-Axis Internal Magnetometer (IM), and internal WAAS Capable GPS Receiver. An Extended Kalman Filter (EKF) using data from the aiding sensors (GPS/magnetometer) is used to correct drift in velocity, attitude and heading. Position accuracy: less than 3 m CEP. Heading accuracy: less than 1.0 deg RMS (magnetic), less than 0.75 deg RMS (with GPS aiding). Pitch and roll accuracy: less than 0.4 deg.|
