From November 9 to 11, 2022, the 15th China Dalian International Maritime Exhibition was held at the Dalian World Expo Plaza. The “Blue Sun” series fiber-optic gyrocompasses from CSSC Navigation made a stunning appearance at the exhibition.
As a high-tech gem in China’s domestically produced communications and navigation sector, the “Blue Sun” fiber optic gyrocompass has garnered widespread attention from attendees and exhibiting partners alike, thanks to CSSC Group’s comprehensive industrial support, over 60 years of accumulated gyrocompass technology, and its remarkable advantages of being “safe, stable, cost-effective, and easy to use.”
Compared with traditional mechanical gyroscopes, the “Blue Sun” series fiber-optic gyroscopes are all-solid-state instruments that feature no moving parts or wear-and-tear components. They boast advantages such as low cost, long service life, light weight, compact size, wide dynamic range, broad precision application coverage, zero drift caused by acceleration, and no swing errors. Additionally, they exhibit flexible structural design and simple manufacturing processes. To date, nearly a hundred sets have been installed on ships and have received widespread acclaim.
Currently, both fiber-optic gyrocompasses and mechanical gyrocompasses share the same scope of application for their respective standards and product certification certificates. However, the product standards for fiber-optic gyrocompasses are significantly higher than those for mechanical gyrocompasses—for instance, fiber-optic gyrocompasses can be used in latitudes above 60°, offer high dynamic accuracy, meet the specifications for high-speed vessels, and provide precise attitude information. Since fiber-optic gyrocompasses have no mechanical moving parts, they suffer from a much lower failure rate, greatly enhancing navigational safety. Moreover, they help shipowners save on procurement costs and maintenance expenses. If we compare traditional mechanical gyrocompasses to “big phones” that use analog signals, then fiber-optic gyrocompasses are like “smartphones” that use digital signals—gyrocompasses are poised to enter the fiber-optic era.
