A precision measurement, with the Alpha Magnetic Spectrometer, of the antiproton-to-proton ratio in the primary cosmic rays is presented. The measurement is made in the rigidity range from 1 to 450 GV and is based on 300,000 antiproton events. The measurement increases the precision and significantly extends the high rigidity range beyond previous observations.
