Asterra

Asterra is an Israeli company that applies satellite data analysis to detect underground water leaks in municipal pipe networks. The company developed technology based on processing SAR (Synthetic Aperture Radar) signals captured by observation satellites to identify anomalous soil moisture — an indicator of subsurface pipe leaks. Detailed public information about the company is limited.

Asterra's primary product, known as EarthSense, analyzes satellite imagery to help water utilities and municipal authorities locate pipe leaks before they surface as visible ground damage. The typical buyer is a public or municipal water utility. The technology sits at the intersection of IoT, remote sensing, and water infrastructure.
