POSPac Automated QC
This application is largely a mechanization of the SBET Solution Quality Assessment guidelines as documented in the POSPac MMS GNSS-Inertial Tools User Guide, so be sure to read through this content at least once!:
POSPac MMS GNSS-Inertial Tools User Guide - Solution Quality Assessment (PDF)
The POSPac Automated QC application concentrates the most important information from the POSPac MMS Message Logs and Plots into a set of windowed tabs to focus the contextual review of your ERS vessel positioning. The density of information on a given tab may at first seem a bit excessive, but such an arrangement allows you to quickly evaluate the ERS data via correlatation to important parameters on the same view. Most of the QC work can be accomplished on the single tab labeled SBET QC. On this tab you can replace the unresolvable errors in the GNSS height and uncertainty time series data with an intepolated signal derived from (known) differential heave, dynamic draft, and water level data.
The ability to discern anomalous ellipsoidal heights for editing is established in this tool via comparisons to the smooth in situ water level and tidal datum. Hence, it is important to include as input for each analysis run - as available: (1) a valid dynamic draft model in the HVF, (2) optional tide zoning data and (3) VDatum.
