Baseline Measurement
RTK
This log contains the most recent matched baseline representing the vector from the reference station receiver to
the remote station receiver. It is expressed in ECEF coordinates with corresponding uncertainties along each axis,
and a time tag. The estimated variance of the baseline in ECEF XYZ coordinates is the same as the XYZ position
variance.
the remote station receiver. It is expressed in ECEF coordinates with corresponding uncertainties along each axis,
and a time tag. The estimated variance of the baseline in ECEF XYZ coordinates is the same as the XYZ position
variance.
It is recommended that you use the trigger ‘on changed’ which will log the selected data only when the data has
changed.
