Undisturbed satel-
lite signal recep-
tion
Successful GPS surveys require undisturbed satellite signal reception, especially at
the receiver which serves as a reference. Set up the receivers in locations which are
free of obstructions such as trees, buildings or mountains.
Steady antenna for
static surveys
For static surveys, the antenna must be kept perfectly steady throughout the whole
occupation of a point. Put the antenna on a tripod or pillar.
Centred and
levelled antenna
Centre and level the antenna precisely over the marker.
