Following the  GNSS Interference, Detection, and Mitigation (IDM) conference at the United Kingdom’s National Physical Laboratory near London, two industry experts on GNSS interference and jamming will lead a GNSS Jamming & Interference: Causes, Consequences, and Solutions Conference later this month.  As the surveying world becomes ever more reliant upon GNSS signals this research becomes ever more important. A marked increase in incidents of GNSS jamming and interference has raised the profile of their effects on users and their equipment.  Equipment. Whether unintended or intentional, in the military domain or civil environments, these incidents have raised concerns among GNSS manufacturers and users about how to avoid or mitigate the adverse phenomena.

During the night of 14 May 300,000 m3 of rock broke off the Valegion mountain and crashed down 1,000 m to the valley floor in the Swiss canton of Ticino, near the village of Preonzo. Thanks in part to Leica Geosystems’ Deformation Monitoring solution GeoMoS local authorities were able to evacuate the valley’s industrial zone and to close the A2...

The 70 employees of the six companies in the industrial zone have resumed their work. But even after this event in Preonzo the Leica Geosystems monitoring system will continue to monitor the slope accurately to protect the people. "More observation points will be installed in an extended zone around the fracture area, which will be continuously monitored for their stability...

Based on the analysis of Leica GeoMoS and extensometer data, the necessary safety measures could be initiated early. The industrial area at the foot of the mountain, which is important for the local economy in this region, could be evacuated in time. The police also closed cantonal roads and the highway. It could not be predicted if the mass would...

The automatic monitoring system has provided continuous information about every movement in the affected zone. Two years ago a Leica TM30 Monitoring Sensor was installed on a stable pillar below the slide area and connected to the Leica GeoMoS monitoring system. Since then the sensor has monitored 15 observation points located inside and outside the danger zone every hour, 24/7...
