OLI-2 (Operational Land Imager-2)

Manufactured by National Aeronautics and Space Administration

Multispectral pushbroom optical imager, primary instrument on Landsat 9 (launched 27 September 2021; USGS operational control from 11 August 2022). Built by Ball Aerospace (acquired by BAE Systems February 2024) under NASA contract. Same 9-band configuration as OLI on Landsat 8, but upgraded to 14-bit quantization (vs 12-bit), yielding 16,384 vs 4,096 grey levels and improving radiometric discrimination of dark targets including closed-canopy tropical forest. 30 m GSD (15 m panchromatic), 185 km swath, 705 km sun-synchronous orbit. With Landsat 8 OLI provides 8-day combined revisit, the operational base for GLAD-L pantropical deforestation alerts.
