BaR-SPOrt (Balloon-borne Radiometer for Sky Polarisation Observations) is an experiment to measure the linearly polarized emission of sky patches aboard a long duration stratospheric balloon. It consists of high sensitivity correlation polarimeters operating in the millimeter wavelength region and coupled to a telescope to obtain a sub-degree angular resolution for direct measurements of the Q and U Stokes parameters. This project shares most of the know-how and sophisticated technology developed for the SPOrt experiment aboard the International Space Station. The instrument design, the various solutions to reduce the systematics and the observing strategy are here described.

Abstract
BaR-SPOrt (Balloon-borne Radiometer for Sky Polarisation Observations) is an experiment to measure the linearly polarized emission of sky patches aboard a long duration stratospheric balloon. It consists of high sensitivity correlation polarimeters operating in the millimeter wavelength region and coupled to a telescope to obtain a sub-degree angular resolution for direct measurements of the Q and U Stokes parameters. This project shares most of the know-how and sophisticated technology developed for the SPOrt experiment aboard the International Space Station. The instrument design, the various solutions to reduce the systematics and the observing strategy are here described.
