GNSS monitoring

Alberding GmbH uses GNSS sensors for the following monitoring applications:

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.

GNSS positioning is used as a basis for billing or critical security processes. The GNSS Status Software of Alberding GmbH is used by customers to check the GNSS system performance.

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.
