Atlas InSAR monitoring studies provide regular and flexible updates of ground and structural motion measurements during the construction, operation and maintenance phase of any site or project.
From weekly to monthly, quaterly or yearly, the frequency of ground motion measurement can be easily adapted to the criticality of the project phase and project specific requirements and can be readjusted at any time.
Atlas InSAR provides customised services, from rapid bulletins providing a quick overview of latest measurements to comprehensive studies following milimetric deformation associated to tunnelling advancements.
Atlas InSAR is a robust, efficient and cost-effective monitoring solution to minimise and mitigate geotechnical risks.
Measuring ground motion from space
Thanks to InSAR technology (Interferometric Synthetic Aperture Radar), the Atlas satellite solution allows for millimetric-precision measurements of ground, buildings or construction sites.
Measurements obtained from satellite cover vast areas without an on-the-ground intervention.
They provide a detailed analysis of the deformations on the terrain, which can be due to works carried out on it or other such events, understanding of the impacted area.
Our Atlas InSAR advanced processing chain can work with any current Satellite SAR Images.
Sixense teams can task SAR Satellites to acquire images over any site every few days to develop customised monitoring programmes designed to provide ground and asset motion information.
Different Satellites will be tasked depending on site and motion characteristics.
Atlas InSAR can work with X, C or L band to ensure the best information is used on each project.
New constellations are being launched and very soon daily imagery will be available for real-time satellite monitoring programmes at a fraction of the cost of traditional monitoring.
Monitor impact of construction works: drawing exact settlement contours
Atlas InSAR monitoring can be applied during the construction phase of any project, providing millions of measurement points with millimetric precision.
The area covered can always be larger that the defined Zone Of Interest, thus Atlas services are a perfect tool to settle subsidence claims and complement in-situ instrumentation.
Monitor tunneling activities: ground settlement due to volume loss
Atlas InSAR monitoring is particularly suited to monitor ground surface displacement resulting from tunneling activities and to measure its impact on existing buildings and infrastructures.
During tunnelling advancement, InSAR Atlas monitoring solutions are used to monitor ground settlement due to volume loss, verify surveying reference points and map any widening of the settlement outside the calculated ZOI.
Early warning tool: detect precursor motion to landslide and slope failures
Atlas InSAR monitoring is an efficient tool to detect precursor motion to landslides, slope failures along large areas such as highways, railways or pipelines and remote and critical infrastructure such as mines, tailing dams and bridges.
Non-linear motion or motion acceleration can be identified, enabling the implementation of early-stage mitigation interventions.
Long term smart maintenance
Atlas InSAR Monitoring is the perfect tool to design long term maintenance programmes.
It provides cost effective measurements and wide area coverage to assess structural health and detect motion likely to cause damages to infrastructures.
Risk Reduction in Mining and tailings dam
Atlas InSAR Monitoring allows customised monitoring programmes to support mining activity.
Atlas InSAR can monitor motion of both underground and open pit mining sites and be used to ensures stability of key infrastructures such as tailing dams, waste dumps and access roads.
