Accuracy

Accuracy is dependent upon various factors including the number of satellites tracked,
constellation geometry, observation time, ephemeris accuracy, ionospheric distur-
bance, multipath and resolved ambiguities.
The following accuracies, given as root mean square, 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.
The baseline precision of a differential code solution for static and kinematic surveys
is 25 cm.
