Upon reaching orbit, it was assigned its Kosmos designation, and received the International Designator 1969-094A.
Kosmos 307 was operated in an orbit with a perigee of, an apogee of, 48.4 degrees of inclination, and an orbital period of 107.7 minutes. It remained in orbit until it decayed and reentered the atmosphere on 30 December 1970. It was the twenty-sixth of seventy nine DS-P1-Yu satellites to be launched, and the twenty-fourth of seventy two to successfully reach orbit.
