GeoMoS is an integrated solution that supports total station, GNSS receivers, levels and geotechnical sensors for an overall

understanding of structural movements.

In large monitoring projects total stations and GNSS receivers can be combined in many different ways to match the

requirements and use a stable reference. The diagram below shows various possibilities.

Total station with co-located GNSS sensor

 A GNSS antenna can be mounted on the top of the measurement hut and applied to the total station stand point with a

three-dimensional offset.

 To orientate the system, a GNSS antenna inside the unstable area is used to update the reference point.

 The GNSS antenna needs a reference station so that baselines can be computed.

Reference points with co-located GNSS sensors

 A total station stand point can be measured and calculated with a free station or distance intersection to reference

points inside the unstable area.

 A GNSS antenna can be mounted on the top of the prism and applied to the point with a height offset.

 The GNSS antenna needs a reference station so that baselines can be computed.

Reference station

 A GNSS antenna can be mounted in a stable area as a reference station. The reference station should be as close as

possible (<3km) to the monitoring area so that the baselines can be computed with the highest accuracy.
