re: Actually...
yes, the carrier wave gave the descent profile.
However -
Even after landing, if Huygens lands in liquid, its bobbing motion
would effect the reception of the carrier-wave; and the resulting oscillation
of the carrier-wave received could be interpreted as strong evidence of the presence of a
liquid surface its floating in
.. is that possible with such small displacements and accelerations - presumably in the order of cm? These must be tiny compared to the descent data. Is the maximum resolution dependent on the sensitivity of the onboard accelerometers or on the observational limit of the doppler shift from Earth?
