Accepting and Rejecting GPS/GNSS Observations

 

 

 

 

When you tell TPC to compute GNSS averages, TPC can help you identify any observations that are outliers. You can then choose to reject those observations.  TPC does not use rejected GNSS observations for GNSS average computations.

You reject observations by UnSelecting (untagging) them in the GNSS Averages dialog.  or by rejecting the raw GNSS data in the Traverse View.

Conversely, you accept them by Selecting (tagging) them.

Accepting and Rejecting GNSS Observations (4:33) - Learn how to accept or reject individual GNSS observations.

Selecting GNSS Outliers  (4:31) - Learn how TPC can select GNSS observations with values that exceed the limits you set RMS, PDOP and coordinate differences.


Rejected GNSS Observations

Rejected GNSS observations are retained with the survey, and can be re-accepted if desired.  They are identified in the Traverse View with a strike through font.

In the example shown here, point 22 was observed twice.  The first observation was a Float with unacceptable RMS and PDOP values, so it was rejected.  The second observation was a Fix, with acceptable values.

In the example shown below, we've selected the point 22 Float observation above and rejected it.
