Key Features
The GN70 is a great addition to Simrad’s current range of IMO-compliant Global Navigation Systems designed for today’s professional. The GN70 features a full-colour display and is designed to work in conjunction with a range of existing IMO-approved smart GPS antennas and GPS compasses. Convenient data interface using SimNet and NMEA 2000
Networking includes simple plug-and-play connection to other N2K-enabled systems
Rotary knob for easy “push-to-enter” operation
IMO compliant
Dedicated hotkeys for position, navigation, heading, AIS and MOB for easy access
LAN can be used to output NMEA 0183/IP messages
5” display for clearer, anti-glare operation
16-bit TFT color display provides wider viewing angle
GN70 can be used with a GPS compass, which has dual IMO compliance certification for use as a primary position AND heading device
GN70 can also be used with the HS80 GPS compass
External RTCM correction for DGPS operation with optional MX610JB junction box.
GN70 is a versatile global navigation system that offers NMEA 2000 (N2K) interface for easy plug-and-play connection to high-performance units such as the AP70/80, Class B-AIS and other N2K-enabled navigation systems. The GN70 can be used as a single display or as redundant multi-unit displays. The NMEA 2000 interface means the user can change things like backlight settings on all Simrad NMEA 2000 electronics on the bridge or switch to a different heading source, all from the GN70 display.
GPS Antenna Options
The GN70 is an IMO-approved navigation system with the MX521A or MX525A/MX5B D/GPS antenna (via the MX610JB –NMEA 2000 to NMEA 0183). The GN70 is also compatible with the HS80 and MX575C DGPS compasses (via N2K connection or via of MX610JB).
