Landsat 8 is launched on 11 February 2013 Earth observation satellite, the US air and space agency NASA . The satellite is the eighth in the series of Landsat satellites. It is equipped with the OLI and TIRS sensors, which deliver images in different spectral ranges of visible light and infrared with pixel resolutions from 15 to 100 m (on the object Earth).

Landsat 8 is part of the Earth Observing Systems (EOS), a long-term research program of NASA that encompasses several missions .

The satellite has sensors for passive recording (measurement) of the earth's surface. The Operational Land Imager (OLI) records images in the following bands (wavelength ranges, resolution):

  • Volume 1 - Coastal aerosol (0.43… 0.45 µm), 30 m
  • Volume 2 - blue (0.45… 0.51 µm), 30 m
  • Volume 3 - green (0.53 ... 0.59 µm), 30 m
  • Volume 4 - red (0.64 ... 0.67 µm), 30 m
  • Volume 5 - near infrared (0.85 ... 0.88 µm), 30 m
  • Volume 6 - Short-wave infrared (1.57… 1.65 µm), 30 m
  • Volume 7 - Short-wave infrared (2.11 ... 2.29 µm), 30 m
  • Volume 8 - Panchromatic (PAN) (0.50 ... 0.68 µm), 15 m
  • Volume 9 - Cirrus (1.36… 1.38 µm), 30 m

The Thermal Infrared Sensor (TIRS) records images in the following spectral ranges:

  • Volume 10 - TIRS 1 (10.6 ... 11.19 µm), 100 m
  • Volume 11 - TIRS 2 (11.5 ... 12.51 µm), 100 m

Orbit

The satellite moves in a polar , sun-synchronous earth orbit (SSE). A characteristic of this orbit is that the satellite passes one point on Earth at the same time every day. Therefore, such earth orbits are often used for meteorological satellites and earth observation satellites .
