Differential code The baseline precision of a differential code solution for static and kinematic surveys is 25 cm.
Static
Kinematic

Accuracy is dependent upon various factors including the number of satellites tracked, constellation geom-
etry, 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.
