  The emission of $\gamma$-rays in jets emanating from the vicinity of
collapsed stellar remnants, in binary systems known as microquasars, is
investigated using a three dimensional relativistic hydrocode (PLUTO), in
combination with two in-house radiative transfer codes. Even though a great
number of stellar systems may be addressed by such models, we restrict
ourselves to the concrete example of the SS433 X-ray binary, the only
microquasar with a definite hadronic content in its jets, as verified from
spectral line observations. A variety of system configurations have been
examined, by employing a hadron-based emission mechanism. The dependence of the
$\gamma$-ray emissions on certain dynamical source properties, such as the
hydrodynamic parameters of the mass-flow density, the gas-pressure and the
temperature of the ejected matter, is simulated. Radiative properties,
especially the assumed high energy proton population inside the jet plasma, and
its effect on the calculated emission, are also examined. Two sets of initial
conditions of the chosen microquasar are employed, in order to cover different
scenarios pertaining to the system under consideration.
