The Landsat 7 carried one instrument: (the Enhanced Thematic Mapper Plus (ETM+) The ETM+ was an improved version of the ETM on Landsat 6. The instrument provided improved spatial resolution. The LANDSAT 7 spacecraft provided improved ephemeris and attitude determination. The LANDSAT 7 spacecraft was built by Lockheed Martin Missiles and Space.
