Calibrate PPP

To calibrate the PPP engine on a prepared seeding point for virtually instant PPP convergence.

PPP seeding significantly reduces time spent in PPP convergence stage to obtain PPPN or PPPF solutions when starting a regular GNSS survey on a specific site. A surveyor can obtain a PPP seeding point for the survey site spending time once for obtaining PPPN or PPPF solution after the standard PPP convergence stage and then use this point any time to start a new PPP survey on this site or to resume a survey if a PPP solution loss occurred. A suitable PPP seeding point should be found and reliably marked on the ground, then accurately surveyed with obtained PPPN or PPPF solution (coordinate averaging is also recommended) and stored as a control point in the current job. Alternatively, the local seeding point with precise coordinates can be imported to the MAGNET Field job from an external source. Such point can be used as the PPP seeding point to calibrate PPP in subsequent survey sessions or imported in new MAGNET Field jobs for virtually instant PPP convergence on this survey site. Depending on the field site layout and survey tasks, multiple PPP seeding points can be prepared and used for calibration.

This dialog provides a quick start of the PPP survey from the PPP seeding point through PPP calibration without spending a sensible amount of time in waiting for a standard PPP convergence required to obtain a PPP solution.

Open this dialog when working in Autonomous/SBAS survey configuration with enabled PPP by clicking in the Topo dialog and selecting the Calibrate PPP command in the dialog menu.
