Satellite Instruments
The Multi Spectral Scanner (MSS) onboard Landsats 1, 2 and 3 covered a 185km swath in four wavelength bands: two in the visible spectrum at the 0.5 to 0.6 micrometers and 0.6 to 0.7 mincrometers and two in the near infrared at 0.7 to 0.8 and 0.8 to 1.1 micrometers. The MSS sensor scanned the Earth's surface from west to east as the satellite moved in its descending (north-to-south) orbit over the sunlit side of the Earth.The resolution of the MSS sensor is approximated as 80 m with an actual sampling resolution of 79 x 56 meters. The MSS sensors aboard Landsats 4 and 5 are identical to the ones that were carried on Landsats 1 and 2. The MSS and TM sensors primarily detect reflected radiation from the Earth surface in the visible and IR wavelengths, but the TM sensor provides more radiometric information than the MSS sensor. The wavelength range for the TM sensor is from the visible (blue), through the mid-IR, into the thermal-IR portion of the electromagnetic spectrum. Sixteen detectors for the visible and mid-IR wavelength bands in the TM sensor provide 16 scan lines on each active scan. Four detectors for the thermal-IR band provide four scan lines on each active scan. The TM sensor has a spatial resolution of 30 meters for the visible, near-IR, and mid-IR wavelengths and a spatial resolution of 120 meters for the thermal-IR band.
