Accuracy

Position to within 10 meters, 2D Root Mean Square (RMS) and 5 meters 2D RMS, Satellite Based Augmentation System (SBAS) corrected.

Velocity to within 24 meters per second.

SBAS is compatible with the Wide Area Augmentation System (WAAS) satellite signal augmenter (United States) and the EGNOS satellite signal augmenter (Europe).

Protocol

The module outputs the following messages:

•GGA - GPS Fix Data

•RMS - Recommended Minimum Specific GPS Data

•GSA - GPS DOP and Active Satellites

•GSV - GPS Satellites in View

•GLL - Geographic Position Latitude/Longitude

•VTG - Course over Ground and Ground Speed.

The GPS module supports NMEA 0183 protocol and SiRF Binary Protocol.
