Objectives of the Product
CrossBandInsights delivers an advanced InSAR monitoring solution that combines data from C-band and X-band satellite missions to overcome limitations of traditional single-band methods. By integrating C-band with X-band’s high-resolution – able to detect sensitive measurements – the system provides enhanced spatial and temporal data diversity. This fusion enables more comprehensive monitoring of ground deformation across varied land cover types and complex environments, addressing challenges faced by civil engineering companies and public authorities.
The technology is designed for flexibility, capable of merging data from any satellite band to ensure future adaptability. It offers highly accurate deformation measurements, allowing precise detection of ground shifts and assessment of structural integrity. This empowers clients to make informed decisions for infrastructure maintenance and risk management. Overall, the solution supports the safety, resilience, and sustainability of critical infrastructure by delivering robust monitoring and actionable data to end-users.
Customers and their Needs
CrossBandInsights targets civil engineering companies and public administrations involved in infrastructure projects, who need to ensure safety across all project phases.
Civil engineering companies face challenges in assessing infrastructure stability and detecting early deformations. Public administrations require comprehensive monitoring for geohazards and urban planning. Current InSAR methods often have limited data sources and inadequate temporal or spatial coverage due to the use of single satellite missions. This makes comprehensive assessment difficult for end users, sometimes leading to delayed responses and increased risks.
CrossBandInsights resolves these issues by combining C-band and X-band satellite SAR data with a new processing algorithm. This fusion provides more accurate and comprehensive deformation measurements, including Line-of-sight (LOS), vertical, and East-West components. The solution is user-friendly, customisable, and affordable, and it enhances the safety, resilience, and sustainability of infrastructure projects.

Product description
The CrossBandInsights solution is an advanced InSAR monitoring product that enhances ground deformation analysis by integrating multi-mission C-band and X-band SAR data. It provides precise deformation measurements in Line-of-Sight (LOS), Vertical, and East-West components. This innovative approach overcomes the limitations of single-mission InSAR by merging data from various satellite sources, significantly improving both temporal and spatial resolution, especially in a mix of different land coverage.
Our new algorithm performs joint processing of these diverse datasets, leading to more consistent time series, improved Atmospheric Phase Screen (APS) estimation, and higher data quality and density, especially in critical areas. Customers, primarily civil engineering companies and public authorities, will interact with CrossBandInsights through our user-friendly, web-based TREmaps platform and standard GIS tools. This platform will visualise the enhanced 1D/2D deformation data, facilitating timely risk identification, proactive maintenance decisions, and comprehensive infrastructure stability assessments.
The innovation lies in this multi-sensor data fusion at the processing level, offering an unparalleled understanding of ground dynamics for urban environments and critical infrastructure.
The product architecture involves several key building blocks:
- PS-SHELL Processing: Initial interferometric processing for each geometry, generating 3D unwrapped phase time series and error bars.
- Joint APS Estimation & Merging Algorithm: A core innovative component that performs a harmonised processing and filtering of atmospheric contributions across multiple geometries.
- 2D Decomposition: Derivation of precise Vertical and East-West deformation components.

Added Value
CrossBandInsights brings added value by overcoming the limitations of current InSAR solutions. While other InSAR solutions only rely on single-satellite missions with limited data, coverage, and assessment capabilities, CrossBandInsights integrates C-band and X-band satellite SAR data. This fusion, combined with a state-of-the-art processing algorithm, will significantly enhance both temporal and spatial resolution, particularly in areas with a mix of diverse land coverages.
Specifically, the solution’s key innovations include multi-mission data integration, enhancing resolution by combining the strengths of C-band (wider coverage) and X-band (denser measurement points, higher sensitivity). This enables a more
comprehensive view of ground deformation, including Line-of-Sight (LOS), vertical, and East-West components. Furthermore, CrossBandInsights is explicitly tailored for civil engineering and infrastructure monitoring, providing precise and relevant insights for this sector. TRE ALTAMIRA’s patented SqueeSAR® processing chain further strengthens this unique advantage. The solution is also designed to be user-friendly, customisable, and affordable, utilising readily available satellite data.
Current Status
The project is currently at the end of the second month. The main activities are focused on the production of the Requirement Review (RR) deliverables. Specifically, efforts include:
- Consolidation of User Requirements, through internal assessment based on existing client feedback from civil engineering and public administration contracts.
- Consolidation of System Requirements, by refining them to ensure alignment with User Needs and User Requirements.
- Identification of key components for Business Plan preparation.
- Refinement of the risk register.
The next set of activities, following ESA’s approval of the RR documents, will focus on designing the workflow required for generating the target product.
