Determination of the descent trajectory of the Huygens Probe during its descent through the atmosphere of Titan on 14 January 2005 is currently under construction. Toward this purpose, measurements from various on-board experiments and system instruments are combined to retrieve the altitude, descent speed and horizontal motion. This task is coordinated by the Huygens Descent Trajectory Working Group (DTWG). The Doppler Wind Experiment (DWE) was designed to retrieve the zonal (east-west) velocity of Huygens. No other on-board experiment can provide this parameter with comparable accuracy. The ground track can also be retrieved from images of the Descent Imager/Spectral Radiometer Experiment (DISR), albeit with less accuracy. Here we present a comparison of the ground tracks retrieved by DWE and DISR. We show that these two independent retrievals of the horizontal motion of Huygens are remarkably consistent.
