8.12 How to identify a borehole using the GPS feature (optional)

An optional GPS feature is available for the GEM5000 gas analyzer. It enables the site
engineer to automatically locate borehole IDs using GPS satellite signal from predefined
borehole IDs uploaded from LSGAM. The GPS reading data is stored for each
measurement reading.

Note: Borehole IDs may be uploaded from LSGAM with or without location
information. If location details are not uploaded the location longitude and
latitude coordinates can be stored when the borehole is located and
downloaded to LSGAM with the reading measurements.

overhead etc. will give a bad fix.
