1.4.4 Pressure Sensor
A stainless-steel pressure sensor is installed in the towfish to provide towfish depth data. This pressure
sensor is designed for continuous use in a corrosive liquid environment and is available in a 3000-psi
pressure range.
1.4.5 SBG AHRS
The SBG AHRS (Attitude and Heading Reference System) option offers a light-weight sensor (45 grams)
that includes: a MEMS-based Inertial Measurement Unit (IMU) that integrates three gyroscopes, three
magnetometers, and three accelerometers and an Ellipse-AHRS running an extended Kalman filter (EKF)
that provides accurate orientation data in both static and dynamic conditions. See the SBG AHRS U
SAGE
section of this manual for more details on this altitude and heading reference system.
