Comnav G1 Satellite Compass Gps Nmea 0183, Nmea 2000

Description

The G1 Satellite Compass is a state-of-the-art electronic navigation data device. It is
capable of providing highly accurate, high-precision position and heading data to a wide
variety of marine Navigation equipment, such as autopilots, sonar, radar, chart-plotters,
AIS receivers & transponders, and many other types of marine devices & systems.
The G1 features fast start-up and signal re-acquisition times, heading & position updates
at up to 20 times per second, and can operate at sustained turn rates up to 45° per
second.
The G1 is a complete Satellite Compass in a single rugged, marine-grade enclosure. It
needs only one single power/data cable, which greatly simplifies installation.
The G1 operates in both NMEA 0183 and NMEA 2000 environments, giving users more
freedom of installation, with the ability to interface with multiple variations of navigation
systems.
The G1 contains a ComNav receiver module (containing two GNSS receivers, a 3-axis
gyro, a 3-axis accelerometer and a 3-axis magnetometer), dual GNSS antennas and a
power supply.
When using DGPS corrections (SBAS, external, or Radio beacon), the G1 is capable of
under one metre precision for position sensing. The GPS antennas inside the G1’s
enclosure are separated by approximately 0.27 metres, which provides better than 0.5
degrees of heading sensing precision.
The gyro accelerometer and magnetometer enhance system performance by providing
heading information for up to three minutes whenever the G1’s normal GPS-based
heading is not available due to signal blockage, or other temporary factors.
