Technical Data GPS1200 115
8.1.2 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 root mean square, are based on measurements
processed using LGO and on real-time measurements.
GPS and GLONASS can increase accuracy by up to 30% relative to GPS only.
Differential code For all receivers, the baseline precision of a differential code solution for static and
kinematic surveys is 25 cm.
