Baseline precision
The following specifications are based on measurements
processed using Leica Geosystems GISDataPro software
and are given as baseline rms (root mean square).
• Differential Phase
• Differential Code
)
Baseline precision is dependent upon various
factors including the number of satellites tracked,
constellation geometry, observation time, ephemeris
accuracy, ionospheric disturbance, multipath and
resolved ambiguities.
