Star-Oddi has introduced the Starmon Compass, a new subsea data logger that integrates multiple sensors in a compact titanium housing. With the ability to measure and log heading, pitch & roll, 3D tilt acceleration, depth and temperature, the high-accuracy data logger is ideal for analysing movement of subsea robotics platforms such as AUVs (autonomous underwater vehicles) and ROVs (remotely operated vehicles).
Users can define horizontal or vertical placement of the logger during setup, and the intuitive software interface offers a real-time view of measurements for convenient pre-deployment testing. The device’s total memory capacity is 2.2 million measurements per sensor parameter, with all measurements recorded simultaneously at a user-defined interval. The temperature probe has a fast response time constant of 2 seconds, and response is immediate on all other sensors.
The Starmon Compass features heading accuracy of better than +/-5°, and pitch and roll accuracy of +/-2°, when within a tilt range of
+/-45°. The depth sensor accuracy is +/-0.3% of the selected calibration range and temperature accuracy +/-0.025°C.
The self-contained logger is enclosed within robust titanium housing for operation even under extreme conditions. The unit’s depth sensor can be calibrated to ranges of 0-50m, 100m, 200m, 500m, 1000m or 2000m. For use at depths greater than 2000m, a customized ultra-high-pressure resistant housing can be provided.
