About
Launched on June 11, 2021, the BJ3A is an AI-powered agile remote sensing optical satellite operated by 21AT. Almost 3 years later in May 2024, 21AT launched 4 additional satellites to create the BJ3 constellation. Each satellite can autonomously determine its flight path and can monitor up to 500 points of interest worldwide with approximately 100 trips daily. These satellites deliver high-resolution remote sensing data and information products to meet global market demands.
