Overview & HistoryBJ3A SpecificationsPricing
Twenty First Century Aerospace Technology launched their first 50-centimeter (cm) resolution satellite, BJ3A, on June 11, 2021 from TaiYuan, China. BJ3A collects 50-cm resolution panchromatic and 2-meter resolution multispectral imagery, including blue, green, red, and near-infrared (NIR) bands. Its swath-width of 23.5-kilometers (km) allows for an impressive daily collection capacity of 750,000 square kilometers (sq km). BJ3A joins Twenty First Century Aerospace Technology’s 80-cm Triplesat satellites as a part of their growing high-resolution constellation.
