[4] Kosmos 76 was launched using a Kosmos-2I 63S1 carrier rocket,[5] which flew from Site 86/1 at Kapustin Yar.

[6] Kosmos 76 separated from its carrier rocket into a low Earth orbit with a perigee of 256 kilometres (159 mi), an apogee of 513 kilometres (319 mi), an 48.8° of inclination, and an orbital period of 92.2 minutes.

It replaced the previous satellite, DS-P1-Yu No.2, launched on 12 February 1965, which had failed to reach orbit due to a second stage malfunction[4]
