The Landsat program started in 1972 with the launch of ERTS, the Earth Resources Technology Satellite, and is active today with Landsat 7 and Landsat 8. The program provides remote sensing data critical to understanding the constantly changing nature of the Earth.  The millions of images acquired help to guide policy makers and land managers who make critical decisions about our environment and natural resources, and have provided research data that can improve food production, measure coastal erosion, and identify the effects of deforestation.

SSAI calibrates remote sensing systems on the Landsat 7 and 8 satellites to ensure consistent, high-quality data and imagery. Our experts assess sensor data and create computer algorithms that keep the data accurate. SSAI is involved from the beginning, testing systems prior to launch, and throughout each satellite’s life cycle, using onboard calibration systems, combined with Earth calibration sites, to provide the most accurate data possible. SSAI’s work has contributed to creating one of the largest continuous research data sets, the Landsat data set, which spans more than 40 years.
