Neutrinos interact with hadronic and leptonic matter only through weak
processes having very low cross-sections. To detect neutrinos with a primary
energy below 1 PeV, most efforts have relied on the use of photo multiplier
tubes and detection of visible Vavilov-Cerenkov light. Above 1 EeV, the use
of
embedded optical detectors becomes unfavourable. Ideas on how to increase
the
detection volume by observing coherent radio frequency emission caused by
the
Askaryan effect have been put forward. Here we investigate how such an
experiment could be performed using a satellite in lunar orbit equipped with
an
electromagnetic vector information sensor. The threshold energy is
determined
for this setup, and the energy dependent sensitivity is calculated using
Monte
Carlo simulations.
