RTK vs. PP Vector standard errors

    Are there standard error settings for RTK vectors? I'm only seeing a GNSS default standard error in  Project settings.  A RTK observation is of lower quality than a post processed GNSS vector.  The default GNSS standard error is 0.016 and 0.033 ft and RTK observations are definitely not that good. It seems that there should be RTK standard error settings and not just generic GNSS?

     

    I have a surveyor who observed a control point in the woods under leaves but also traversed in with a robot total station and using both types of observations TBC weighted the position more towards the RTK observations.

    Yes agreed, RTK/Network RTK/Static all need the ability to be weighted differently/separately in a Network Adjustment.

     

    Using the Baseline Processor option as the source for Standard errors is often inadequate, as N/RTK Obersvations can sometimes be given an overoptimistic precision estimate and hence too high of a weighting in an adjustment.
