Landsat satellite:  A satellite that collects multispectral images.  At various times it uses 1) a Return Beam Vidicon (RBV) device, 2) the Multispectral Scanning (MSS) device, and 3) the Thematic Mapping (TM) scanning device.  Landsat also relays data from ground observation stations.  Landsat was originally called the ERTS or Earth Resource Technology Satellite.
