SmartStation Accuracy
)
Measurement precision and accuracy in position and accuracy in height are
dependent upon various factors including the number of satellites tracked, constel-
lation geometry, observation time, ephemeris accuracy, ionospheric disturbance,
multipath and resolved ambiguities. Figures quoted assume normal to favourable
conditions.

Accuracy
Initialisation
Position accuracy:
Horizontal: 10 mm + 1 ppm
Vertical: 20 mm + 1 ppm
When used within reference station networks the posi-
tion accuracy is in accordance with the accuracy speci-
fications provided by the reference station network.
