At SatSense, we leverage radar satellites with varying wavelengths to tailor our solutions to specific applications. The wavelength of radar influences sensitivity to displacement, geolocation precision, and the ability to penetrate vegetation, enabling highly specialised insights.
While C-band Sentinel-1 InSAR data excels at capturing wide-area phenomena, at low cost, with a spatial resolution of 5 x 20 meters, it can fall short for monitoring individual structures like buildings and bridges.
To address this, SatSense is expanding its capabilities by incorporating commercial X-band InSAR data for major UK cities, complementing our nationwide C-band dataset.
This innovative approach aligns with SatSense’s mission to make ground movement data more accessible and actionable for diverse applications.

High-resolution data unlocks new possibilities by offering:
