Huygens Atmospheric Structure Instrument (HASI)

WHAT IT MEASURES:

HASI will determine the principle atmospheric properties of Titan: density, temperature, pressure and electrical, as a function of height above the Titanian surface. Some information on wind and lightning will also be provided.

HOW: Pressure, temperature and accelerometery sensors will determine the pressure, temperature and density profile of the atmosphere. Electrical properties will be investigated using a suite of electrical sensors.

The University of Kent has prime responsibility of the accelerometery sub-system which incorporates a single axis high sensitivity servo and lower sensitivity three axis piezo-resistive accelerometers.
