The Vector G2ComNav G2 GNSS GPS 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, chartplotters, AIS receivers & transponders, and many other types of marine devices & systems. The ComNav G2 GNSS 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 90° per second. The ComNav G2 GNSS is a complete GPS Compass in a single rugged, marine-grade enclosure. It needs only one single power/data cable, which greatly simplifies installation.
There are two models available – the ComNav G2 GNSS Satellite Compass and the ComNav G2B GNSS Satellite Compass. They are identical, except in their Differential GPS (DGPS) correction features:
The G2 GPS Satellite Compass supports multiple RF front ends - enabling tighter coupling of measurements from separate antennas for use in heading-based products. Users will achieve excellent accuracy and stability due to the more accurate code phase measurements, improved multi path mitigation, and fewer components.
The G2/B’s GPS antennas are separated by 50 cm between their phase centers, resulting in 0.5° rms heading performance. The G2/B provides heading and positioning updates of up to 20 Hz and delivers positioning accuracy of 1.0 m 95% of the time when using differential GPS corrections from beacon (G2B only) or from Space Based Augmentation Systems (SBAS).
The G2/B also features technology that enables ComNav GPS Satellite receivers to utilize old differential GPS correction data for 40 minutes or more without significantly affecting the positioning quality. The G2/B is less likely to be affected by differential signal outages due to signal blockages, weak signals, or interference.
GPS Sensor Specifications
Beacon Receiver Specifications (G2B)
Gyro: Provides smooth heading, fast heading reacquision and reliable < 1º heading for periods up to 3 minutes when loss of GPS has occured (static conditions)
Tilt Sensor: Assists in fast start up of heading solutions
