Kongsberg Discovery is marking a milestone in its inertial navigation portfolio’s 30th anniversary with the launch of the Seapath 385 navigation system. The system is designed to enhance precision in hydrographic surveying by leveraging advanced navigation algorithms and integrating a range of satellite signals, including GPS, GLONASS, Galileo, Beidou, and QZSS, alongside geostationary satellite signals.

Scientists at Draper Laboratory have patented a celestial navigation system called a sliced-lens star tracker, which in its early form can achieve 50-meter accuracy in GNSS-denied environments. Improvements are expected as the technology evolves. Vehicles of all kinds may be able to benefit when using this system for navigating by the stars.
