KRIA’s attendance to the Aosta Valley regional project called Smart Specialisation Strategy (S3) has given a great push to the development of our GEO Surveyor 2.0 device specifically designed for landslides and avalanches monitoring.
Following the suggestion of the geological department called “Sezione Attività Geologiche” of the Autonomous Region of Aosta Valley, a prototype of our GEO Surveyor 2.0 device has been approved to be tested in the pilot site of Fontainemore in order to monitor the Pic de Molér side that rises above the small town of Lillianes. Other pilot sites on different sides of Monte Bianco mountain are still operating.
GEO Surveyor 2.0 is installed in Gressoney valley (Fontainemore locality), in order to monitor the Pic de Molèr slope.
The hundreds meters front of the Pic de Molér side with its huge and unsteady rock blocks has already been being monitored by the regional authorities. The electricity for the higher part of the Gressoney Valley, the Regional Road (unique communication route with Gressoney) and the houses within the town of Lillianes represent infrastructure and areas exposed to risk so that it was necessary to raise the monitoring level.
Besides the new software functions and the complete hardware review, this device has the great news of the total energy independence. A battery pack that has to be buried in order to reduce temperature variations keeps the GEO Surveyor 2.0 device always operating; the batteries take energy from solar panels and wind. A charge controller balances the available energy sources providing the right energy quantity for the full operation of the device itself and also keeping an appropriate charge level to the batteries.

The GEO Surveyor 2.0 device is also equipped with transmission systems based on IP technologies both wireless and wi-fi offering the maximum flexibility for the communications of the detected events.
This system has been designed with very low dimensions so that it can be handled and installed without any specific machinery. Furthermore, considering the very small occupied area and its own power supply, installation can be easily replicated even in different contexts.

In 2018 KRIA found the perfect opportunity to develop the new GEO Surveyor 2.0: the call for participation at the Smart Specialization Strategy – S3 of Aosta Valley.
Thanks to the bid, we are accelerating in the research and development of the new GEO Surveyor 2.0. The final product will be very small, easy to install and easy to use.
The idea of “What you see is what you get” remains the same: thanks to the optical technology of GEO Surveyor, the outputs are immediate to interpretate!
In September 2019, Planpincieux glacier started to accelerate his descending motion. The glacier is located under the famous Grande Jorasses, Mont Blanc massif, and in this momenti, its front is on a big slope change. The high temperatures, recorded also in the mountain areas, encouraged the acceleration of the ice mass. There aren’t houses and people in danger, but the local street of the Val Ferret does.
Our technicians installed a GEO Surveyor system, for the continuous monitoring of the front of the glacier, in combination with a radar system developed by an other company.

In addiction, this site is perfect in order to test the new functions of GEO Surveyor, that is able to generate motion maps on the image plane. This is made by the continuous comparison of the HD images taken by the system:
Due to the positive response of the first GEO Surveyor, installed for the La Saxe rockfall monitoring, KRIA continued to develop the product. The new version of the GEO Surveyor is compact, autonomous and easy to install.
The italian face of Mont Blanc was the test site for the new GEO Surveyor. Here the device is monitoring a slope very far: 6,5 km from the device to the target. This is very interesting as a test-site, providing useful data to the KRIA R&D compartment.

Despite the difficulties of the miniaturization, the Brenva test-site confirmed that this is the right direction!
In 2019, KRIA participated in the call for tenders “S3 – Smart Specialization Strategy, and the R&D compartment started to develop the official miniaturized version, with the novelty of a solar and wind energy kit, in addiction to new mechanical parts and software.
The first GEO Surveyor 2.0 is installed in Fontainemore (AO), in order to monitor the rockfall on the slope of Pic the Molèr.
