-BNC can derive coordinates for a rover position following the Precise Point Positioning (PPP) approach. It uses either code or phase data in ionosphere free linear combinations P3 or L3.

 By default BNC applies a PPP solution using an ionosphere free P3 linear combination of code observations. Tick 'Use phase obs' for an ionosphere free L3 linear combination of phase observations.
