New product
Modern ships rely on accurate positioning systems for safe and efficient navigation. A Marine GPS Navigator provides continuous information about a vessel's position, speed, course, and time by receiving signals from Global Navigation Satellite Systems (GNSS).
Marine GPS Navigators are installed on almost every commercial vessel, including container ships, bulk carriers, oil tankers, LNG carriers, offshore support vessels, fishing vessels, naval ships, research vessels, and passenger ships.
Leading manufacturers such as Furuno, JRC, Koden, Simrad, Hemisphere GNSS, and Trimble have developed highly reliable GPS navigation systems that are trusted by the global maritime industry.
SM MARINE SERVICE™ supplies complete marine GPS navigators, GPS antennas, display units, spare parts, repair services, calibration support, and worldwide technical assistance.
A Marine GPS Navigator is an electronic navigation system that determines a vessel's position using signals received from navigation satellites. Unlike a standard consumer GPS, commercial marine GPS navigators are designed for continuous operation in demanding marine environments and integrate with multiple bridge systems.
Typical navigation data includes:
Marine GPS Navigators provide essential data to:
Furuno is one of the world's leading manufacturers of commercial marine navigation equipment. Furuno GPS navigators are installed on thousands of merchant ships, fishing vessels, offshore support vessels, and government ships worldwide.
SM MARINE SERVICE™ supports sourcing, repair, replacement, and worldwide supply of Furuno GPS navigation equipment and spare parts.
JRC (Japan Radio Co., Ltd.) has long been recognized for manufacturing reliable commercial marine navigation equipment. JRC GPS navigators are widely installed on cargo ships, tankers, offshore vessels, and fishing fleets.
SM MARINE SERVICE™ supplies Furuno, JRC, and many other commercial marine GPS navigation systems, including new, used, and professionally reconditioned equipment, along with technical support, spare parts, repair services, and worldwide shipping.
Koden Electronics Co., Ltd. is a well-established Japanese manufacturer of commercial marine navigation equipment. Koden GPS Navigators are widely used on fishing vessels, workboats, coastal cargo ships, pilot boats, and merchant vessels because of their dependable positioning accuracy and user-friendly operation.
SM MARINE SERVICE™ supplies complete Koden GPS navigation systems together with spare parts, repair support, and worldwide delivery.
Simrad manufactures advanced marine navigation equipment for commercial vessels, offshore operations, research ships, fishing fleets, and specialized marine applications. Simrad GPS systems are designed for reliable positioning and seamless integration with other bridge electronics.
Hemisphere GNSS specializes in high-performance GNSS positioning and heading technologies for professional marine applications. Its products are widely used on offshore vessels, hydrographic survey ships, dredgers, and precision navigation platforms.
Trimble is recognized globally for precision positioning technologies. In the marine sector, Trimble GNSS receivers are commonly used for offshore construction, dredging, survey operations, port development, and specialized commercial vessels requiring highly accurate positioning.
Septentrio develops professional-grade GNSS receivers for demanding marine applications. These systems are widely used where robust positioning performance and interference resistance are essential.
Many commercial ships use DGPS (Differential GPS) or advanced GNSS antenna systems to improve positioning accuracy. The antenna is a critical component of the navigation system because it receives satellite signals continuously, even in challenging weather conditions.
Marine GPS systems may experience operational issues over time due to environmental conditions, hardware aging, or installation problems.
SM MARINE SERVICE™ supplies Koden, Simrad, Hemisphere GNSS, Trimble, Septentrio, and many other commercial marine GPS navigation systems, including complete units, antennas, spare parts, repairs, calibration support, and worldwide logistics.
One of the biggest advantages of commercial marine GPS navigators is that many faults can be repaired by replacing individual modules instead of the complete system. This reduces maintenance costs and minimizes vessel downtime.
SM MARINE SERVICE™ supplies genuine, compatible, used, and professionally reconditioned marine GPS navigator spare parts for a wide range of commercial navigation systems.
Commercial marine GPS navigators often operate continuously for many years. With proper diagnostics and professional servicing, many systems can be restored without requiring complete replacement.
Although GPS systems do not require calibration in the same way as gyro compasses, periodic performance verification is essential.
Recommended checks include:
A Marine GPS Navigator is a core component of the Integrated Bridge System (IBS). Position and navigation data from the GPS are shared with multiple onboard systems to support safe and efficient vessel operation.
Reliable GPS data ensures accurate chart positioning, radar overlay, AIS reporting, voyage recording, and automated steering functions.
Routine maintenance helps maximize the reliability and service life of marine GPS navigation equipment.
Although modern ECDIS systems often include integrated positioning functions, dedicated marine GPS navigators remain essential because they provide:
Dedicated GPS units also provide valuable redundancy in the event of failures affecting other navigation equipment.
Commercial vessels commonly use Furuno, JRC, Koden, Simrad, Hemisphere GNSS, Trimble, Septentrio, and other professional marine navigation systems.
