LONG-TERM, BACKGROUND MONITORING
Designed as a long-term, background monitoring tool, the GMS (Geotech Monitoring Station) monitors vast mine areas for long periods of time of many months to many years. It specialises in background monitoring in open cut pits and highly vegetated slopes, and detecting and measuring deformation on tailings dams, dumps and cuttings.
Prism Points are highly accurate, can be scanned from long ranges, and are the fastest to scan.
A Pixel Point allows for the measurement of areas that are difficult, dangerous or even impossible to reach using prisms. Their quantity and placement is at the whim of the user, with the capacity to use as many points as required, 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 laser uses a high power telescope that is also used for camera imaging, with an extreme level of zoom not found in traditional cameras. This allows customers to remotely inspect areas from their desk, at a level often not possible in a standard pit inspection.
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.
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 automatically tracks and locates its Prism Points with every scan, known as collimation. There are two lasers on board; one for measuring deformation, and one solely dedicated to prism collimation.
Even if a prism is moving, this functionality ensures that its location is never lost, without ever relying on historical data for coordinate information. The GMS hunts for, finds and locks Prism Points into their exact position with each and every scan.
Prism Points can be monitored from the ultra-long range of 5000 metres. Pixel and Precision Points can reach 2000 metres on a white surface, making for reliable monitoring at ~1000m for a typical rock face.
By incorporating its data alongside data from radars, InSAR, piezometers, extensometers and more, a holistic view of the pit can be realised.
