4.1 Guidelines for Correct Results with GNSS Surveys
Undisturbed satellite
signal reception
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.
Steady instrument for
static surveys
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.
Centred and levelled
instrument
Centre and level the instrument precisely over the marker.
