This graph shows the CNAV derived heave solution compared against the RTK heave solution. The standard deviation of the difference is 0.043m.

Why does this look better than the DGPS?? (for showing heave changes) Checking...

This is the RTK heave solution when the RP is "moved" 2.6m aft of its actual location.
