Description

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 can obtain DGPS information from many Space-Based Augmentation System (SBAS) sources (in areas where compatible ones are available & operational), including WAAS, EGNOS, MSAS, SNAS, GAGAN and others. The G2 can also accept DGPS information from an external data source.
  • The G2B has an additional integrated beacon receiver module, which allows it to use conventional terrestrial DGPS Radiobeacon signals to obtain DGPS information, in addition to SBAS sources & external DGPS data sources.
  • 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.
