We analyze the spin modulation of the current of a boom-mounted positive biased spherical Langmuir probe observed with the Viking experiment. The satellite perturbs the probe current by two distinct effects: (1) photoelectrons emitted by the low potential part of the satellite; (2) capture of ambient electrons. These two effects are shown to be strongly dependent on the magnetic field orientation with respect to the probe-satellite axis. We quantify experimentally and theoretically the range of such effects. We then deduce some basic rules for electron energy and density measurements and for the design of satellite-borne Langmuir probe experiments.
