Abstract :
A novel design of a wind sensor for the surface of Mars is described. This sensor is to be included in the Rover Environment Monitoring Station (REMS) to be launched as a part of the Mars Science Laboratory in 2009. A 2D hot film anemometer composed of four hot points and a reference point has been conceived and implemented in the preliminary design model. It uses a closed thermal feedback loop based on thermal sigma–delta modulation. In this paper, the first results obtained in a Mars-like environment are shown, and indicate that sensitivities are expected to be in the range of 0.5 m/s and 10° in wind speed and direction.
