Satellite-based leak detection technology "Astera Recover"

A technology for extracting leak investigation locations across the entire target area using satellite image analysis.

By analyzing images captured from satellite radar emitting L-band microwaves and detecting the unique reflection characteristics of tap water or sewage mixed with soil, we can identify suspected leak locations within a radius of 100 meters. We streamline fieldwork by narrowing the sound survey target distance to an average of 1/10, maximizing the absolute number of leak detections in a short period, including underground leaks that are difficult to visually detect. The results of the field survey can also be input on-site using communication devices such as smartphones linked to GPS, allowing for real-time sharing with the office. Unlike deterioration predictions, we can provide actual soil moisture observation data, enabling us to conduct comprehensive leak investigations in an "efficient" and "cost-effective" manner. ● Purpose Comprehensive screening survey for leak investigations (narrowing down the range of on-site sound surveys) * On-site sound surveys are not included in this service. ● Features Shortened duration for comprehensive surveys (analyzing the entire target area in about 2 months) Increased efficiency and reduced costs for sound survey work (narrowing the survey distance to an average of 1/10) Early detection of underground leaks (reducing effectiveness decline and secondary disaster measures) Digitalization of field surveys (utilizing GIS pipeline data and communication devices) Optimization of pipeline renewal plans (using survey results as foundational data for pipeline diagnostics)
