Kosmos 307 was operated in an orbit with a perigee of 212 kilometres (132 mi), an apogee of 2,023 kilometres (1,257 mi), 48.4 degrees of inclination, and an orbital period of 107.7 minutes.^[1][4] It remained in orbit until it decayed and reentered the atmosphere on 30 December 1970.^[4] It was the twenty-sixth of seventy nine DS-P1-Yu satellites to be launched,^[1] and the twenty-fourth of seventy two to successfully reach orbit.^[5]
