InSAR - Satellite based ground and structure deformation monitoring made simple.
Atlas-InSAR™ is our in-house InSAR solution for remote monitoring of ground deformation with millimetric accuracy.
Radar satellite interferometry (InSAR) represents a non-intrusive surveying method renowned for its ability to precisely measure millimeter-scale movements of terrain features across expansive regions, spanning both urban and rural landscapes.
This technique capitalizes on synthetic aperture radar (SAR) imagery captured by satellite sensors.
.
Atlas-InSAR™ harnesses raw satellite data, meticulously processed from satellite constellations, to furnish comprehensive time-series data on ground motion, boasting an impressive density of up to 20,000 points per square kilometer.
.
Whether employed independently or in tandem with traditional instrumentation, Atlas-InSAR™ offers unparalleled insights into your site or infrastructure, all without the need for ground-based installations.
Delve into the depths of historical data and uncover invaluable insights with Atlas™ InSAR solution. Harnessing the extensive SAR data archive dating back to 1992, Atlas -InSAR™ enables retro studies, offering a unique perspective on ground movements over time.
By tapping into this reservoir of information, you gain a deeper understanding of past vulnerabilities, ensuring your construction designs are finely tuned to prevailing conditions. With Atlas-InSAR™, embrace the power of retro studies to elevate your project's performance while safeguarding against potential claims.
Atlas-InSAR™ harnesses the power of high-resolution satellite imagery, delivering results with an impressive resolution down to 1m x 2m in the best conditions and a density of up to 20,000 Pts/Km2, even across expansive territories. This groundbreaking capability grants you access to an unprecedented wealth of information, facilitating in-depth analysis and understanding of your site's dynamics, irrespective of its scale, infrastructure, or urban context.
Consider the implications of dewatering activities, which can exert substantial influence over considerable distances. Thanks to Atlas-InSAR™ measurements, you can precisely delineate the perimeter at risk, mitigating the potential challenge of losing reference points for ground instruments. With Atlas-InSAR™, you gain the ability to vigilantly monitor ground movements, detecting even the slightest fluctuations with precision. Armed with these insights, you can swiftly implement corrective measures, optimising your project's performance with timely actions.
ATLAS™ InSAR offers an affordable complement and/or alternative to traditional ground deformation monitoring methods. By providing measurement layers of many thousands to a few million measurement points (depending on the surface), ATLAS™ enables you to gather more data in a shorter time frame compared to precise leveling, which monitors around 100 points per day in a specific area.
Moreover, ATLAS™ can provide more than 20,000 measurement points per km2 in urban environments, making it an ideal solution for large-scale projects. By deploying a combination of complementary technologies such as precise leveling, Automatic Total Station, and InSAR, you can significantly lower the cost of ground deformation monitoring while delivering richer information.
With ATLAS™, you can optimise your project's budget without sacrificing accuracy or precision.
Beyond Monitoring™ is our web based delivery platform for all of your projects. With an architecture optimised for “big data”, visualisation and analysis of millions of data points is smooth and intuitive.
Being able to smoothly handle a few million data points from Atlas-InSAR was one of the non-negotiable specifications of the platform and the result is above expectations.
One of our projects in Auckland is generating 7,600,000 data points every 11 days and has been running for 40 months. Navigating this substantial database to locate and analyse critical areas is straightforward.
Atlas-InSAR™ is a versatile tool that can be applied to various environments, from urban to rural settings, to monitor almost any type of asset, including buildings, airports, ports, dams, roadways, railways, and mines.
One of the key strengths of Atlas-InSAR™ is its ability to monitor settlement induced by underground excavation and dewatering for tunnel construction, mining, and other projects. Its capacity to monitor large areas simultaneously with high density and accuracy is unmatched, making it an invaluable tool for these industries.
Given its exceptional performance, Atlas-InSAR™ is rapidly becoming a standard in ground and structure deformation monitoring, empowering you with the insights you need to make informed decisions and optimise your project's performance.
No wonder Atlas InSAR is becoming a standard in ground & structure deformation.

The Muswellbrook Bypass is a critical infrastructure project planned along the New England Highway in New South Wales. It is designed to improve travel times, enhance freight efficiency, and increase road user safety. The bypass will divert through traffic away from Muswellbrook, reducing congestion caused by intersections and buildings close to the existing highway.
Sixense has been engaged to provide advanced InSAR monitoring for the project. This monitoring enhances safety, supports the assessment of historical and potential ground movements, and ensures that construction proceeds within acceptable tolerances, particularly in areas influenced by nearby mining activity.

The 10.5 km Torrens to Darlington (T2D) tunnel project is the final piece of one of Adelaide’s most important transport routes, the North-South Corridor (NSC).
In order to gain a clearer understanding of the initial conditions, the Department of Infrastructure and Transport (DIT) enlisted Sixense to conduct historical ground deformation monitoring along the tunnel alignment. At the end, we ended up analysing the entire Adelaide Basin. This provided the team with invaluable data for their geotechnical analysis.

Crossrail (The Elisabeth Line) is a 117-kilometre railway that traverses London from East to West. The construction phase of the project began in 2009 with an estimated cost in excess of £17 billion. The main challenge, for which the ATLAS InSAR technique was pivotal, was monitoring the 21km of twin tunnels running from Paddington to Stratford and Canary Wharf below the city.
Crossrail is the first construction project actively using InSAR as a technique to reduce monitoring costs. ATLAS InSAR monitoring was performed before and during the construction of the tunnels and is still ongoing to analyse residual settlement. The study area monitored includes a corridor 2km wide over the tunnel alignment, covering a total area up to 36 km2.
