What sensors does the Landsat 9 satellite carry?

Landsat 9 carries the same instruments that are on the Landsat 8 satellite but with some improvements:

  • Operational Land Imager (OLI) for reflective band data.

  • Thermal Infrared Sensor (TIRS) for the thermal infrared bands.

  • OLI has a slightly improved signal-to-noise ratio over Landsat 8's OLI.

  • Landsat 9’s TIRS is a Class-B instrument with a five-year design life and a key improvement of stray light correction, an issue that was discovered on Landsat 8’s TIRS (Landsat 8's TIRS is a Class-C instrument with a three-year design life).

  • As with Landsat 8, Landsat 9 has higher imaging capacity than previous Landsat missions, allowing for more valuable Earth observations to be added into the USGS Landsat archive.
