Guidelines for Correct Results with GNSS Surveys

Successful GNSS surveys require undisturbed satellite signal reception, especially at
the instrument 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
occupation of a point. Place the instrument on a tripod or pillar.
Centre and level the instrument precisely over the marker.
