InSAR

Interferometric Synthetic Aperture Radar (InSAR) utilizes the phase information within SAR imagery to precisely measure how the Earth’s surface changes over time. By comparing multiple SAR data collections, InSAR can detect displacement with millimeter precision across vast areas, regardless of weather conditions, day or night. This capability is crucial for identifying subtle changes that may indicate risk, instability, or emerging events.

Historically, InSAR, while a powerful Earth observation tool for detecting millimeter-scale surface change, has been constrained by inconsistent revisit intervals, unpredictable acquisition geometry, manual coordination, and fragmented workflows. Capella Space’s taskable InSAR transforms this by making data operational, automated, and continuous, leading to earlier detection, more robust time-series analysis, and faster decision-making.

Capella’s InSAR solution offers high-frequency monitoring with a 3-day revisit capability, allowing for earlier detection of deformation and continuous tracking of change over time with consistent, reliable time-series data. The system features automated InSAR data collection, where users define their area of interest, orbit, and cadence, and Capella handles the rest, including automatic scheduling, collection, and delivery. Precision repeat geometry is ensured through tight orbital control and a repeat ground track orbit, providing the stability necessary for accurate monitoring. Furthermore, a dual-orbit advantage, operating in both Sun-synchronous orbit (SSO) and Mid-inclination orbit (MIO), enables multi-angle observation and supports comprehensive analysis.
