You are now ready to begin a standalone PPP survey.

When you connect to the receiver with NTRIP Starpoint Pro, the user needs to connect to the Starpoint/Starpoint Pro mount point to begin streaming corrections.

Your initial solution will be CPPP (Convergence PPP) in MAGNET Field.

You will then have a PPPN (PPP Normal) solution as the RMS comes down. Convergence time is about 10-30 minutes.

The NTRIP version of Starpoint Pro currently only outputs a PPPN solution.

When the NTRIP corrections service is lost, the PPP solution will remain usable for up to 8 minutes.
