Measurement Precision and Position Accuracies
Important Note
Measurement precision and accuracy in position and in height are dependent upon various
factors including number of satellites, geometry, observation time, ephemeris accuracy,
ionospheric conditions, multipath etc. Figures quoted assume normal to favourable conditions.
Times can also not be quoted exactly.
Times required are dependent upon various factors including number of satellites, geometry,
ionospheric conditions, multipath etc.
The following accuracies, given as root mean square, are based on measurements processed
using LGO and on real-time measurements.
