Which one of the following is not a sensor of Indian remote sensing (IRS) satellite ?

  • A.LISS - III
  • B.PAN
  • C.WiFS
  • D.TM

Answer: D

The sensor that is not on IRS satellites is TM.

TM, the Thematic Mapper, is the multispectral sensor of the American Landsat 4 and 5 satellites, operated by NASA and the USGS.

The other three are Indian sensors: LISS-III (Linear Imaging Self-Scanning sensor) flew on IRS-1C, 1D and Resourcesat; PAN, the panchromatic camera, also flew on IRS-1C and 1D; and WiFS, the Wide Field Sensor, gave wide-swath coverage on the same satellites.
