Multipath
Multipath is when GNSS satellite
signals are reflected off nearby
objects, such as buildings or
cars, causing an erroneous
signal to be received by the
GNSS antenna. This can cause
errors of several meters.
To reduce multipath, where possible collect
data in an open environment away from
large reflective surfaces and with a clear view
of the sky.
Occupation time
at a point
Occupation time is the time
spent at a point logging GNSS
positions.
For point features, remain at the feature and
log a number of GNSS positions to obtain an
averaged position.
When collecting line and area features,
collect them using averaged vertices.
