SAR data for infrastructure inspection

1. Capella Space

(Best starting point for InSAR)

United States · X-band SAR

Capella explicitly offers InSAR-ready single-look complex (SLC) imagery and a taskable deformation-monitoring service. Its published offering includes three-day repeat cycles and multiple orbital geometries, which are useful for building repeatable ground-motion time series. NASA also documents a Capella archive exceeding 30,000 images and support for InSAR analysis.support.capellaspace.com+2

Why shortlist it: A particularly strong fit if you want a managed, recurring collection program rather than sourcing isolated images.

2. ICEYE

Finland / United States · X-band SAR

A strong candidate for large-area and frequent monitoring programs. ICEYE offers multiple imaging modes, from high-resolution spotlight acquisitions to wider-area scans, and has a large SAR constellation. Its satellite data has also been evaluated by NASA's commercial satellite data program.www.observationdata.com+2

Why shortlist it: Useful when the pipeline network is extensive, rapid repeat collections matter, or you need to monitor many sites under a common service arrangement.

Verify carefully: Confirm the availability of repeat-track SLC pairs and the acquisition schedule for your specific corridor; high revisit frequency alone does not guarantee usable interferometry.

3. Umbra

United States · X-band SAR

Umbra provides high-resolution Spotlight and Scan imagery, with resolutions advertised as fine as 25 cm. NASA describes its data as suitable for scientific applications requiring radiometric quality and geolocation accuracy.science.nasa.gov+5

Why shortlist it: A compelling alternative for high-resolution inspection, localized deformation investigations, and procurement teams that value transparent data licensing and published pricing.

Verify carefully: Establish whether its repeat acquisitions, SLC data, and interferometric processing support your required deformation time series—not just detailed individual images.

4. Airbus Defence and Space

Europe · X-band SAR and broader Earth-observation portfolio

Airbus is worth evaluating if you want a mature Earth-observation supplier with SAR, optical imagery, and elevation products available through a broader portfolio. NASA's 2026 commercial-data agreements include Airbus SAR imagery.science.nasa.gov+5

Why shortlist it: A potential fit for enterprise procurement, multi-sensor corroboration, and programs that benefit from established geospatial-data delivery workflows.

5. MDA Space

Canada · C-band SAR heritage

MDA is another candidate for programs where established C-band SAR data and longer-term archive continuity matter. Its SAR offerings and NASA's commercial SAR agreement make it worth including in a formal comparison.science.nasa.gov+1

Why shortlist it: A useful alternative to X-band providers, particularly when you need to compare radar wavelengths and their performance over different vegetation and terrain conditions.

These are recommendations for a procurement shortlist, not a definitive, independently verified ranking of operational reliability. The providers have different sensors, collection modes, and delivery commitments, so the best choice depends on the actual pipeline corridor and required monitoring cadence.

What matters most for pipeline ground-motion monitoring?

I would evaluate vendors against these five requirements before signing a contract.

One especially relevant finding comes from a NASA-affiliated technical study of commercial SAR. Its tests of Capella and ICEYE found that image resolution and geolocation performance could meet specifications, but interferometric coherence varied with terrain and acquisition geometry. The study also identified limitations in repeat-orbit availability and orbit control at the time of testing. These findings reinforce why vendors should be tested on your actual corridor rather than selected from published resolution figures alone.ntrs.nasa.gov

My recommended procurement approach

1. Start with Capella and ICEYE. Request sample SLC stacks and a demonstration of displacement time-series processing over representative pipeline terrain.
2. Include Umbra as a third bidder. Ask it to demonstrate repeat-pass suitability and the complete InSAR workflow for your area of interest.
3. Benchmark against an independent reference. Compare satellite-derived motion with ground-based measurements where feasible. Use an independent geotechnical assessment to investigate anomalies.
4. Test a complete monitoring cycle. Measure the proportion of usable interferograms, displacement uncertainty, spatial coverage, missed collections, and end-to-end delivery time. Include vegetated, built-up, and sloping sections if those occur along your route.

For long-term monitoring, consider combining commercial SAR with the free European Sentinel-1 archive where coverage and data quality are adequate. The commercial service can supplement the baseline with higher-resolution or more frequent acquisitions.

Bottom line: Capella is my first candidate for a dedicated InSAR-oriented service; ICEYE is a strong alternative for frequent, large-scale monitoring; and Umbra is worth benchmarking for high-resolution collection. I would make the final decision based on validated deformation measurements, repeat-pass availability, and contractual service levels—not a universal vendor ranking.

One question would help narrow this down: Is your pipeline corridor primarily in vegetated rural terrain, mountainous terrain, or urban and industrial areas? That factor can substantially change which SAR configuration will be most reliable.
