We recently began using an SP80 RTK base and rover system with a Carlson data collector running the latest version of SurvCE. After performing a topo we compared the coordinates spit out from the data collector with ones processed through Starnet and got some substantial differences in the horizontal and vertical location of some points, though most were consistent. Carlson tech support has been worthless in trying to resolve this issue. Has anyone experienced anything similar?
With the base and rover, are you sure you have the correct geoid applied and the projection set? Nine times out of ten that's the reason for substantial differences in height.
The projection and geoid are correct. Like I said, the majority of points are consistent, but a handful are not.
