The large-scale structure of the Milky Way's magnetic field is not well understood. Faraday rotation measurements can provide information about the line-of-sight magnetic field towards pulsars and extragalactic sources. Polarization of background starlight provides plane-of-the-sky magnetic field orientation information, but for many more lines-of-sight. Several existing theoretical models of the large-scale Galactic magnetic field were used to simulate models of near-infrared background starlight polarization observations, with attention specifically focused on returning values of Galactic position angle versus Galactic latitude. Combined with ongoing observations, like the Galactic Plane Infrared Polarization Survey (GPIPS), these simulations will provide testable constraints on models of the large-scale structure of the Galactic magnetic field.
