IBIS ArcSAR Lite / Performance

The world's most trusted slope monitoring radar

IBIS-ArcSAR has set new standards in the mining industry, and with its outstanding performance has become the technological solution that leads and inspires the slope monitoring market. IBIS-ArcSAR is designed for fast deployment and robustness to ensure the highest safety standards to manage risk conditions with confidence. Whether it is a strategic or tactical positioning, IBIS-ArcSAR delivers unprecedented performance and data quality to make critical decisions.

To meet the industry’s demands for a very flexible system that can cover different mining conditions, IBIS-ArcSAR is offered in two configurations: Lite and Performance. IDS GeoRadar has always be custom tailored to match any monitoring scenario, not locking you into one solution that doesn’t meet your current needs or future challenges. The upgrade from Lite to Performance can be made at any time with just a mouse click, resulting in maximum return of the initial investment and added value for the future of the mine. 


We have always been convinced that hardware availability must match with highest level of data reliability to achieve effective critical monitoring at any time of the day and under all weather conditions.  IBIS ArcSAR, with its proven 99+% hardware availability, provides outstanding data quality thanks to the unique IDS GeoRadar advanced atmospheric processing algorithm, result of years of development together with our customers. As a low maintenance but high-performance instrument, IBIS-ArcSAR can operate without the use of a diesel generator up to 90% of the time, thanks to its very low power consumption, extended autonomy and integrated green energy solutions (solar and wind). 

IBIS-ArcSAR is the only radar in the mining industry to provide continuous 360° scanning of pit walls with an end-to-end scan time that matches the radar acquisition time. By employing a fully rotational military-rated  slip ring technology it maximizes robustness with minimal moving parts, getting rid of unwanted exposed cabling and expensive maintenance.
IBIS-ArcSAR can operate up to very long range  (5000 meters), with a very short scan time (360° in 40s; 180° in 20s) always maintaining the highest resolution with light data for the mine network. 
The exceptional spatial resolution defines the minimum extent of detectable area, even at high range and sub bench scale. One single radar pixel is enough to trigger an alarm, no artificial oversampling is needed to increase image definition. 

IBIS-ArcSAR is also the first complete 3D SAR radar to use the proprietary mimo antenna array and DTM automatic generation. The system also features an integrated HD panoramic camera (85 Mpx for 180° panoramic view) that provides real-time images of pit walls and instant visualization of critical areas. The integrated GNSS sensor ensures on-the-fly automatic georeferencing of the radar unit during set-up.
Data quality is always guaranteed by IDS GeoRadar’s state-of-the-art atmospheric correction and intelligent data management system.


Integrating seamlessly into the Guardian FPM360 suite, IBIS-ArcSAR can dramatically expand overlap areas of multiple IBIS radars to exploit the unique TrueVector capabilities, delivering a rich geotechnical environment. 
One solution combines radar data, prism displacement and slow movement analysis into a single versatile platform.

Powerful and user-friendly, the IBIS Guardian software manages slope stability risks in open pit mining operations. IBIS Guardian enables fast interpretation and therefore fast reaction time for vital real-time information delivered by the IBIS-ArcSAR system.

Reliable data with flexible alerts in real time
Highly accurate displacement data is provided to monitoring specials in real time using the most advanced Automatic Atmospheric Correction algorithm. Easy analysis of mines’ radar data is possible using the Eagle-Vision camera to add fully geo-referenced 3D maps and high-resolution panoramic images.

Unique Multi-Scale processing and the ability to store long-term projects enable resolving up to four orders of displacement magnitude, making this an essential tool for the support of:

  • Mine Design
  • Mine Planning
  • Risk Mitigation Strategies.

IBIS Guardian offers alert messaging options and comprehensive geotechnical analysis tools. Monitoring specialists are immediately alerted in the event of slope displacement by means of various instant messaging options such as email, SMS or pop-up alerts.

Advanced data integration for even clearer understanding of slope stability
Automatically import different total station and GNSS datasets, for example from Leica GeoMoS© or Trimble T4D©, to enable even clearer understanding of slope stability. Monitoring experts can compare prism and GNSS displacement trends with IBIS radar data to understand movement behavior much faster. Stereonet charts are also available for quick and immediate representation of displacement data.

Through an advanced automatic export tool and the unique External Public Interface (API), IBIS data can be exported and displayed in third-party platforms for geotechnical monitoring.

Full Pit Monitoring 360 & TrueVector
IBIS Guardian offers Full Pit Monitoring (FPM) capabilities, stitching merging together data sets from multiple IBIS radar systems onto a single radar map3D georeferenced topography. Real-time full pit data provides monitoring experts with a complete view of the entire pit for managing slope hazards.

Benefits of the IBIS Guardian FPM include:

  • Streamlining tasks from multiple workstations into one unique software platform
  • Reducing work processes
  • Saving valuable time needed for making decisions

With TrueVector technology, IBIS Guardian is able to resolve the spatial direction of displacement vectors for hundreds of thousands of overlapping radar pixels being monitored simultaneously by two or more radar systems, with sub-millimetric accuracy. No prisms, markers or reflectors are needed on slopes to rapidly resolve displacement information.

Beyond the mine
Thanks to the powerful IBIS data server, monitoring projects and critical alerts can be accessed from anywhere.

There is no need to deal directly with radar data or interfere with IBIS Guardian projects. Using integrated IBIS Dispatch, dispatch operators are provided with easily understood, real-time alerts coming from IBIS units or even multiple pit operations.

Corporate offices can also take advantage of IBIS Dispatch to centralise alerts generated at different mine sites.
