Launch
Kosmos 347 was launched from Site 86/4 at Kapustin Yar, atop a Kosmos-2I 63SM carrier rocket. The launch occurred on 12 June 1970 at 09:30:02 UTC, and resulted in the successful deployment of Kosmos 347 into low Earth orbit. Upon reaching orbit, it was assigned its Kosmos designation, and received the International Designator 1970-043A.
Orbit
Kosmos 347 was the thirty-third of seventy nine DS-P1-Yu satellites to be launched, and the thirtieth of seventy two to successfully reach orbit. It was operated in an orbit with a perigee of 214 kilometres (133 mi), an apogee of 1,970 kilometres (1,220 mi), 48.4 degrees of inclination, and an orbital period of 107.1 minutes. It remained in orbit until it decayed and reentered the atmosphere on 7 November 1971.
