Kosmos 76 separated from its carrier rocket into a low Earth orbit with a perigee of 255 kilometres (158 mi), an apogee of 499 kilometres (310 mi), 48.7 degrees of inclination, and an orbital period of 92.09 minutes. It decayed from orbit on 16 March 1966. Kosmos 76 was the third of seventy nine DS-P1-Yu satellites to be launched, of which all but seven were successful. It replaced the previous satellite, DS-P1-Yu No.2, which had failed to reach orbit due to a second stage malfunction
