Gyrocompass is a compass that shows a vessels course relative to the true north.
Scientists were working on gyroscope whole XIX century and first construction was pattented by Martinus van den Bos (1885) but he never managed to built an working model.
First gyroscope was built by Arthur Krebs (1890) – but it was not pointing to the north yet.
Regarding first working gyroscope pointing to the north there are 2 theories (European and American):
• It was Hermann Franz Joseph Hubertus Maria Anschütz-Kaempfe - a German scientist and inventor, founder of the company Raytheon-Anschütz. In his quest to navigate to the North Pole by submarine, he became interested in the concept of the gyrocompass. In 1905 he founded the first company to manufacture gyroscopic navigation instruments, which he designed.
• It was Elmer Ambrose Sperry who built gyroscope in the United States in 1905 and the same year started manufacture as well.
Because Mr. Anschütz presented first working model of gyrocompass (pointing to the north) in 1903 already – it seams that he was first.
Gyrosphere for Anschutz Gyrocompass STD20 and STD22
Today Raytheon-Anschütz produces the IMO-Approved STD22 Digital gyrocompass that generally works still in the same way. Evolved from the widespread STD20 the STD22 is the most advanced gyrocompass in the market. Operational safety was dramatically increased due to a patented data transmission technology that completely replaces the use of slip rings.
For retrofits the STD22 combined with a course transducer can replace almost all compasses that can be found on any vessel. Contact Raytec Marine for a solution (from parts only up to turnkey) on your vessels.
Besides the Gyrocompass STD22, Raytheon-Anschütz also produces a Satellite Compass, the STD21 for non-IMO applications. As a low cost solution it is ideal for Yachts and Jots.
