About
BJ3N3 is an advanced agile remote sensing optical satellite operated by 21AT, launched August 24, 2022. It delivers 0.3 m panchromatic and 1.2 m multispectral imagery across a 11.5 km swath from a 610 km sun-synchronous orbit. The satellite supports precise mapping at 1:10,000 scale with multi-directional targeting, stereo, and tri-stereo acquisition modes. Its 11-bit dynamic range across panchromatic (450–900 nm) and four multispectral bands ensures excellent radiometric fidelity for demanding Earth observation applications.
