4.1 Guidelines for Correct Results with GNSS Surveys
Successful GNSS surveys require undisturbed satellite signal reception, especially at the instru-
ment which serves as a base. Set up the instrument in locations which are free of obstructions
such as trees, buildings or mountains.
For static surveys, the instrument must be kept perfectly steady throughout the whole occupa-
tion of a point. Place the instrument on a tripod or pillar.
Centre and level the instrument precisely over the marker.
