At Scandinavian Micro Systems, we remain true to a simple philosophy: we contribute to your safety at sea by developing and installing highquality, precision navigation instruments for your ship. And we’ve been doing it for over 30 years. The Optical Bearing Device (OBD) is a perfect example of our commitment. It enables navigators to quickly double-check their ship’s position by making fast and accurate optical observations and thus detecting possible GPS errors, interference or spoofing.
