The deformation monitoring is used to detect movements in structures or in the earth's surface. Three-dimensional
movements of up to a few millimetres can be detected by continuously determining the GNSS antenna position. Due to
the advantages of the satellite-supported measurement method, GNSS sensors make a valuable contribution to geomonitoring,
either individually or in combination with other sensors.
GNSS services are used to provide the active official spatial reference in surveying (e.g. SAPOS) and agriculture.
Correction data are derived from software packages using data of permanent GNSS reference stations. The
GNSS services are supervised by monitoring stations in order to check the correction data and the derived
accuracy and availability information. For these tasks the
A10-RTK sensor and the
AQC software are used.
For critical safety applications, a preliminary check of the effect of DGNSS or RTK correction data is required.
In pre-broadcast monitoring, GNSS correction data are checked with
data streams from monitoring stations before they are transmitted. The resulting integrity information is attached
to the data streams and transmitted to the users.
The telemetry and positioning systems of Alberding GmbH are used autonomously for positioning moving platforms
and other objects (e.g. traffic signs). If these objects move outside specified zones, the sensors can notify a
predefined group of people via SMS or e-mail.
