“BOREAS allows for solid state, north seeking, or gyro compassing at a frac- tion of the size, weight, power, and cost of systems currently on the market,” said
Orr. “That makes it viable to take sys- tems that are currently using magnetic heading and move them across to much more reliable gyro compassing or north seeking technology.” As technology in general starts to evolve more quickly, Orr sees a number of trends in the maritime and subsea sector that could be drivers for
DFOG technology and Boreas D90 for a generation to come. “What we’re seeing is there’s a big focus on autonomy in the marine and subsea marketplace at the moment,” said Orr. “So companies are investing a lot of money in automating both subsea systems and also sea sys- tems.
