Synthetic aperture radar (SAR)
NISAR's July release makes calibrated L-band radar data more widely available, though it has so far been validated only at selected sites. Public scientific data and commercially ordered imaging serve different needs. Before using one in place of the other, compare frequency, resolution, how often the satellite revisits and how quickly the data is delivered.

Core thesis
Capella Space, ICEYE, and Umbra operate commercial SAR constellations. Unlike optical satellites, SAR works through clouds and at night. Ukraine war demonstrated SAR's military value — tracking troop movements regardless of weather. Interferometric SAR measures ground subsidence to millimetre precision, critical for infrastructure monitoring and earthquake risk.
State of the art (2026)
Commercial radar imaging is led by a few operators. ICEYE runs the largest constellation and Umbra flies a smaller high-resolution fleet. Capella Space was bought by the quantum computing company IonQ in 2025. On the public side, the NASA-ISRO satellite NISAR launched in July 2025. NASA released provisional L-band data on 20 July 2026. That data is calibrated but has been validated at only a limited number of sites, and ISRO publishes the S-band products separately. Free scientific data and paid commercial imaging serve different needs, so compare frequency, resolution, revisit time and delivery speed before treating one as a replacement for the other.
