Preparing for a data collection session
Upon initially powering on or enabling the GNSS location fea-
ture, expect the first geo - referenced location to take place within a
minute or so of operation on a clear day. The GNSS location ar-
row icon (page.7) will transition from clear to a shaded color as
more satellites or higher level of precision are reached. The GNSS
location icon gives an indication of the quality of the satellite fix.
A minimum of 5 received satellites are necessary for a location
fix. Achieving 10 or more satellites will yield high quality posi-
tion data.
For Best Results
Geo - Location referencing will show the best accuracy when the
meter is kept active for 6 minutes or more. The positioning data
will be most accurate when the sky is clear, there are few, if any,
reflective surfaces, and there is an unobstructed view of the sky.
Optimally, the meter should have a clear view of the sky above a
15 degree elevation. When possible, keep clear of buildings, bod-
ies of water, and other reflective surfaces that may distort the sig-
nal triangulation. Solid objects, such as trees, buildings, aircraft
and even the user themselves can block satellite signals.
