DGPS kit OP20-56 with GP021S antenna for GP170

Designed for professional navigation, the FURUNO DGPS kit OP20-56 with GPA021S antenna is a precision augmentation solution for the GP-170 GNSS navigator. This kit enables the GP-170 to operate in DGNSS (Differential Global Navigation Satellite System) mode, providing enhanced stability and reliability for merchant ships, large yachts, ferries, and commercial vessels.

GNSS Precision and Reception

The GP-170 system, enhanced by this kit, integrates a new GPS circuit and the GPA-021S antenna, ensuring improved positioning accuracy. It is compatible with GPS, GLONASS, DGNSS, SBAS (Satellite-Based Augmentation System), and SLAS (Sub-meter Level Augmentation Service) systems. The GPA-021S antenna is designed for better noise rejection and high tolerance to multipath fading, enabling position updates at 10 Hz (every 0.1 seconds) for stable vessel tracking. The GPA-021S antenna weighs approximately 1 kg and is typically supplied with a 10-meter cable.

GP-170 Display and User Interface

The GP-170 features a 5.7-inch color LCD screen with a VGA resolution of 640 x 480 pixels and a brightness of 700 cd/m². It offers seven different display modes, including two customizable ones, for clear visualization of navigation data. The GP-170’s memory capacity allows storage of 10,000 waypoints, 100 routes, and 3,000 tracks. It includes a front USB port for routing data and parameter import/export, as well as an IEC 61162-450 compliant LAN interface for efficient network integration within a bridge system.

Connectivity and Compliance

The GP-170 provides extensive connectivity with four NMEA0183 ports, one Ethernet port, and one USB port. It supports Bridge Alert Management (BAM) alerts per IMO MSC.302 (87) and complies with IMO performance standards, including IACS UR E27, IMO MSC.112 (73) for GPS, MSC.113 (73) for GLONASS, MSC.114 (73) and IEC 61108-4 for DGNSS. The system supports dual configuration for backup needs, enabling navigation data sharing between units. It serves as a position sensor for other navigation and communication equipment such as radar, AIS, ECDIS, autopilot, and fishfinder.
