In our previous video tip, we showed how TBC’s “Processing Services” routine can be used to easily send Trimble GNSS raw static data files to the National Geodetic Survey’s “OPUS” service for post-processing. In this installment, we’ll show how a processed OPUS result can be conveniently imported straight from your email back into TBC, then be used to refine the coordinates of an RTK survey originally performed using an autonomous “here” base position!

This video will demonstrate how to take the XML attachment which accompanies the OPUS-corrected email results when submitted via TBC’s Processing Services; drag & drop these into an existing RTK project; then “merge” & shift the original base position …and former RTK measurements, to the newly refined based coordinates! This can be an extremely useful technique for RTK surveys performed in areas with limited or difficult to access control.
