Deformation monitoring is used to detect movements of civilian structures or in the earth's surface. Three-dimensional
displacements of up to a few millimetres can be detected by continuously determining the GNSS antenna position. Due to
the advantages of the satellite-based measurement method, GNSS sensors make a valuable contribution to geo-monitoring,
either used alone or in combination with other sensors.
GNSS services are used to provide the active official spatial reference in surveying (e.g. SAPOS) and precision agriculture.
Real-time corrections are generated by software packages using measurement data from permanent GNSS reference stations.
Dedicated monitoring stations and quality control applications supervise the GNSS service, continuously monitoring
the availability and quality of the corrections and the achievable positioning accuracy.
For these tasks, Alberding GmbH offers the A10-RTK sensor and the
For safety-critical applications, a preliminary check of the effect of DGNSS or RTK corrections is required.
During pre-broadcast monitoring, the GNSS correction data is applied to the raw
data streams of monitoring stations and checked before transmission. The resulting integrity information is attached
to the correction streams and transmitted to the users.
The Alberding telemetry and positioning systems are used autonomously to determine the position of 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 text message or e-mail.
