Post Processing Data Collection
Data collection for post processing involves storing GPS raw
data to a file on disk. The file is usually stored on the

then PC software is used to process the base line
measurements. This section describes:

¾ What to do with the data.
Note: If you wish to log post processing data simultaneous
with RTK data collection, please see the previous section.
