GPS Coordinates

GPS measured points is not uploaded to the data collector from TGO
or TTC. However, this is not a problem since the coordinate system
definition is uploaded, and this will define the transformation from
plane to geodetic.
Note: TGO will only import GPS measurement vectors from Survey
Pro .RAW files that were collected with an EPOCH25 GPS receiver or
with a Trimble GPS receiver when the Trimble System Extension
module was authorized in Survey Pro at the time of data collection.
TTC will import GPS measurement vectors from any Survey Pro
.RAW file, regardless of the type of GPS receiver used to do the data
collection or the modules authorized in Survey Pro at the time of
collection.
