Utilizing electromagnetic radar technology, the ST-1N / I1 from Hyundai Welding Co., Ltd. (Pohang) is designed to provide reliable navigation and collision avoidance capabilities under IMO SOLAS requirements. This model operates in X-Band and S-Band frequencies, ensuring comprehensive coverage for maritime applications. The radar system is DNV-approved, making it a trusted choice for vessels requiring robust and certified equipment. Common issues with the ST-1N / I1 include magnetron end-of-life after 5,000 to 8,000 hours of operation in magnetron models, antenna rotation motor bearing damage after 30,000+ hours, display backlight failure, heading marker misalignment, and waveguide moisture ingress due to compromised pressurization. To mitigate these issues, it is recommended to keep a spare magnetron on board for magnetron models, with a lead time of 1-3 weeks. Regular maintenance is crucial for optimal performance. The magnetron should be replaced every 5,000-8,000 hours, and the antenna bearing should be lubricated annually. Weekly performance monitor tests are required by IMO regulations, and an annual inspection is recommended to ensure all systems are functioning correctly.
