Scientific paper

It is noted that the application of advanced optical data links permits both a reduction of antenna diameters and position determination error by orders of magnitude. For a typical mission to Jupiter, three different optical technologies are examined, which use CO2, Nd:YAG, and semiconductor diode lasers. The first two systems make it possible to realize coherent optical transponders which are required for a two-way Doppler measurement with the optical carrier. Direct detection with pulse position modulation is assumed for the semiconductor laser system.
