Long-Term, Background, Prism and Prismless Solution
The GMS-Dual (Geotech Monitoring Station) is a long-term, background monitoring tool designed to track and monitor both prisms and virtual points.
The system allows for measurement of areas that are difficult, dangerous or even impossible to reach using prisms. It specialises in monitoring open cut pits and highly vegetated slopes, and detecting and measuring deformation on tailings dams, dumps and cuttings.
The GMS-Dual delivers all the same features as its sister model, the GMS-Prism, plus many more. Both systems are equipped with a range of features that take them well beyond the capabilities of typical robotic total stations, including smart data capture, intuitive visualisations and a powerful camera suite.
The GMS-Dual monitors using both prisms (Prism Points) and virtual points (Pixel and Precision Points) placed directly on the rock.
Prism Points are highly accurate, can be scanned from long ranges, and are the fastest to scan. Pixel Points require no prisms, are fast to scan, and can be placed in as many locations as required.
Precision Points are ideal for pinpointing and observing key areas of concern, especially on rough, jagged rock faces and areas on the wall with a low incidence angle to the laser. Although taking longer to scan, the resultant accuracy in these scenarios is unmatched.
The GMS-Dual measures and displays deformation for all types of points with high accuracy. Multiple streams of deformation data are collected, with different atmospheric timeframe processing. All measurements are processed and ready for analysis at the end of each scan, enabling the early detection of movement.
For additional accuracy, the vector movement in 3D is also measured for prisms, empowering users to better understand ground conditions and get the benefits of both readings. Users can analyse individual points, or average groups of points in any configuration.
The GMS-Dual can be rapidly deployed using the automatic grid scan feature. The software automates a grid of Pixel Points once the scan area is specified, allowing for immediate scanning. Using up to 1000 Pixel Points with dense pixel spacing, the system ensures that no point of interest is overlooked.
No longer relying on basic spreadsheets, all data from the GMS is intuitively visualised in GroundProbe’s patented software, SSR-Viewer. Users are given access to its entire suite of charting, analysis and alarming tools, gaining the full benefits that our radar customers are accustomed to on top of a range of features developed specifically for the GMS.
All data collected can also be directly imported into data aggregation software, MonitorIQ.
The GMS is equipped with dual cameras offering three levels of zoom. The wide-angle camera captures broader scope images of the points while monitoring occurs. SSR-Viewer then automatically aligns all photographs into one panoramic scene to produce a vivid, high definition image. With the second camera attached to the telescope, users can not only precisely see and control the location of their points, but also capture its details.
