STA File

A station file contains any decoded camera marks, antenna heights and station names. It is read automatically when adding a GPB file to a project. The first line of a station file should contain $STAINFO.

The station file may have a header record. If a Pos record is detected, it will be imported automatically when adding the GPB file as a base station to the project. The following is a description of the header format.

The station file format also handles event marks. Saving a project with event marks loaded brings the event marks into the station file. The following is the event mark format.
