Accuracy is dependent upon various factors including the number of satellites tracked, constel-
lation geometry, observation time, ephemeris accuracy, ionospheric disturbance, multipath and
resolved ambiguities.
The accuracies, given as root mean square, are based on measurements processed using
GeoMax Geo Office and on real-time measurements.
The use of multiple GNSS systems can increase accuracy by up to 30% relative to GPS only.
