Remember this port selection
If this option is checked then the software will skip the port scan, which makes it
quicker when the software is run. Normally the GPS-Base will remain on the same port
so it is not necessary to visit this page each time.
If the GPS-Base cannot be found on the saved port then it will scan all the ports, which
can take time. It is best to have the GPS-Base on and connected before starting the
software.
Configuring the GPS-Base
Before the GPS-Base will output corrections it needs to know the position of the GPS
antenna. This can be restored from a file (i.e. using a position that has been saved), it
can be restored from the GPS-Base, it can be entered by the user or the GPS-Base can
average its position for a period of time to find an approximate location for the antenna.
There is some discussion at the end of the manual describing the benefits of each
technique. In general it is sufficient to average for 3 minutes. For repeatable work save
the averaged location and then restore this location from a file or use the “Save Position
To GPS Base” feature. To be accurate to a map it will be necessary to average for a
long period of time (and hope that the person who made the map did this too, which
they may not have).
When this page is first entered the software will default to “Average Position”. If a
GPS-Base with a valid position is detected then the software will quickly change to the
“Leave Unchanged” option.
