The ST-50G / I1 is a radar system designed for maritime navigation and safety, manufactured by Hyundai Welding Co., Ltd. in Pohang. This radar operates on both X-Band and S-Band frequencies and complies with the International Maritime Organization's Safety of Life at Sea (SOLAS) regulations. Utilizing electromagnetic radar technology, it provides reliable detection and navigation assistance essential for maritime vessels. Common issues that may arise with the ST-50G / I1 include end-of-life conditions for the magnetron after approximately 5,000 to 8,000 hours of operation, bearing damage in the antenna rotation motor after 30,000 hours, and backlight failure on the display. Additionally, heading marker misalignment and water ingress in waveguides due to compromised pressure sealing can occur. To ensure optimal performance and longevity, it is recommended to keep a spare magnetron on board for magnetron models. The lead time for spare part delivery is between 1 to 3 weeks. Regular maintenance includes replacing the magnetron every 5,000 to 8,000 hours, annual lubrication of the antenna bearing, and weekly performance monitoring tests as per IMO requirements. An annual inspection is also advised to maintain the radar's certification and operational integrity.
