Accuracy
Accuracy is dependent upon various factors including the number of satellites
tracked, constellation geometry, observation time, ephemeris accuracy, ionospheric
disturbance, multipath and resolved ambiguities.
The following accuracies, given as

s
quare, are based on measurements
processed using LGO and on real-time measurements.
The use of multiple GNSS systems can increase accuracy by up to 30% relative to GPS
only.
Differential code
The baseline precision of a differential code solution for static and kinematic surveys
is 40 cm. The measurement of accuracy is compliant with ISO
17123-8.
