ICEYE, a 14-year-old Finnish SAR satellite manufacturer, has launched an open data initiative providing publicly accessible satellite imagery and videos captured from 2023 to present. The company operates a constellation of satellites capable of high-resolution imaging through clouds and adverse weather, with CEO Rafal Modrzewski recently meeting with leaders including Ukraine's Zelenskyy and India's Modi.

Canada's RADARSAT satellite constellation, with three generations launched since 1995, captures synthetic aperture radar imagery and ship tracking data for maritime surveillance, disaster management, and climate research. The third constellation (RCM), launched in 2019, comprises three satellites capable of imaging 95% of Earth's surface daily regardless of weather conditions.
