Since the RTK technology allows calculating position of the object with centimeter-
level accuracy, it is more sensitive for the GNSS antenna placement conditions, in
contrast to the standard accuracy GNSS modules which able to determine the
position with meter-level accuracy in difficult signal reception conditions.
Examples of recommended GNSS antenna placement are shown below.
Recommended GNSS antenna placement
Recommended environments:
•
Open sky, elevation angle mask not less 15 degree above horizon. Absence of
objects nearby: buildings, cars, trees,
peoples
,
etc.
•
A ground plane under the GNSS antenna reduces the effect of multipath, in case
of using simple and cheap (not geodetic-class) GNSS antenna. A metal sheet with
a radius not less 10 cm, a metal roof of a building or a machine can be used as the
ground plane.
•
Ensure that other electronic devices are not located close to the GNSS antenna.
