 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.
