5.2 Accuracy
Accuracy is dependent upon various factors including the number of satellites
tracked, constellation geometry, observation time, ephemeris accuracy, iono-
spheric disturbance, multipath and resolved ambiguities.
The following accuracies, given as
r
oot
m
ean
s
quare, are based on measure-
ments processed using Zeno Office and on real-time measurements.
The use of multiple GNSS systems can increase accuracy by up to 30% relative
to GPS only.
