Precise measurement of the foreground synchrotron emission, whichcontaminates the faint polarized cosmic microwave background radiation (CMB),is a major challenge for the next-generation of CMB experiments. To addressthis, dedicated foreground measurement experiments are being undertaken atradio frequencies between 2 and 40 GHz. Foreground polarized synchrotronemission measurements are particularly challenging, primarily due to thecomplicated frequency dependence in the presence of Faraday rotation, and arebest recovered through broad fractional-bandwidth polarization measurements atfrequencies $\lesssim 5$ GHz. A unique opportunity for measuring the foregroundpolarized synchrotron emission will be provided by the 15-m SKA-MPG telescopeoperating in the frequency range 1.7 to 3.5~GHz (S-Band). Here, we present thescope of a Southern sky survey in S-Band at 1 degree angular resolution andexplore its added advantage for application of powerful techniques, such as,Stokes $Q$, $U$ fitting and RM-synthesis. A full Southern-sky polarizationsurvey with this telescope, when combined with other on-going efforts atslightly higher frequencies, will provide an excellent frequency coverage formodeling and extrapolating the foreground polarized synchrotron emission to CMBfrequencies ($\gtrsim80$~GHz) with rms brightness temperature better than 10~nKper 1 degree$^2$. We find that this survey will be crucial for understandingthe effects of Faraday depolarization, especially in low Galactic latituderegions. This will allow better foreground cleaning and thus will contributesignificantly in further improving component separation analyses and increaseusable sky area for cosmological analysis of the \textit{Planck} data, and the\textit{LiteBIRD} mission in the future.
