GPS Location
When the MESA is receiving GPS coordinates it will tag saved files with GPS information. It will
also tag signals in signal lists with GPS coordinates.
Note: In order to receive GPS coordinates, the GPS Adapter (see page 18) must be inserted into one of
the MESA's USB ports. To improve GPS reception, especially on cloudy or overcast days, use a USB
extender cable to physically locate the GPS adapter further from the MESA unit.
The MESA provides several options for determining the accuracy of the received coordinates.
HDOP - Horizontal Dilution of Precision is a value used in satellite navigation to represent
positional precision. The smaller the number, the more precise the Latitude & Longitude
coordinates are.
Satellites in View: This is the number of satellites from which the MESA is receiving positional
data.
Reception Strength: Using HDOP & the number of satellites in view, the MESA will estimate the
quality of the coordinates received. Possible values for Reception Strength are Weak, Fair, and
Strong.
