The EX-1's default NMEA sentence has a
position accuracy of 5 decimal places,
with a minimum resolution of
approximately 1~2 cm. You can extend the
position accuracy to 7 decimal places,
with a minimum resolution of
approximately 0.2 mm, by following these
steps.
Default precision:

$GNGGA,155544.00,3705.92075,N,12015.88656,E...
After setting to high-precision mode:
$GNRMC,160415.00,A,3705.9207505,N,12015.8865595,E...
$GNGGA,160415.00,3705.9207505,N,12015.8865595,E...
When RTK positioning is active and the
antenna remains stationary, the track points may slowly
drift within a 1 cm range, this is normal. |
