GPS Pathfinder Office Software Getting Started Guide 79 4 Tutorial Exercise 3: Differentially correcting the field data The data has been collected in the field by the three field crews. It has been transferred back to the office computer and now you need to process it. This exercise introduces you to the concepts of: · · postprocessed differential correction base data It shows you how to: · differentially correct SSF files Postprocessed differential correction Postprocessed differential correction can significantly improve the accuracy of GPS positions collected in the field. The Differential Correction wizard compares the collected GPS data with base data collected at a known location at the same time that the field data was collected. The process produces a . cor file that contains a new set of GPS positions that are corrected. Base data Many regions have reference stations that can supply the base data required for differential correction. The GPS Pathfinder Office software provides a list of some stations that you can use to obtain base data. The base data for the tutorial is on the Trimble FTP site and is available by selecting the GPS Pathfinder Office tutorial base files provider from the list in the Select Base Provider dialog. 80 GPS Pathfinder Office Software Getting Started Guide Tutorial 4 To differentially correct the field data: 1.
