* SBAS enabled as default. Specifications will vary depending on the number of satellites used, obstructions, satellite geometry (PDOP), multipath effects, and atmospheric conditions. Accuracies stated to 95% CEP (Circle of Error Probable), meaning that 95% of the time the position readings will fall within a circle of the stated radius.
