The LSPE project is a mission of the Italian Space Agency based on the development of two instruments aimed at joint surveys of the cosmic microwave background (CMB) polarization at large scales and with very high precision. A further purpose of the mission consists in the validation of new technologies developed in Italy necessary for a future large international mission in this field. The two instruments are: i) SWIPE that is based on bolometric radiometers operating at frequency channels located between 145 GHz and 240 GHz and that will be embarked on a stratospheric balloon; ii) STRIP, which is a radio telescope consisting of an array of coherent radiometers operating at 43 GHz and 90 GHz to be installed at the Astronomical Observatory of Tenerife.
