Is Cellular RTK Networks Accurate Enough for GPS Landforming?

Cellular RTK is not recommended because the base station is generally too far away.  For landforming, we need the highest accuracy possible otherwise you'll be shifting more soil than you need and not finishing the topography to the design surface which may result in drainage problems remaining.

For more details on the accuracy of these corrections, see Virtual Reference Station (VRS) for OptiSurface Landform

We recommend a base station within 1 mile or 1.6km, ideally at the edge of the field.
