Mission details:

• Another quartet of O3b satellites for broadband internet distribution was launched on Dec 18, 2014. Each satellite carries an array of 12 Ka-band spot beam dishes and provides capacity for internet providers in the developing world. The Soyuz ST-B (Arianespace version of the Soyuz-2-1b) took off from the Centre Spatial Guyanais and placed the Fregat S/N 133-01 upper stage in a -1167 x 192 km x 5.3 deg suborbit at 1936 UTC Dec 18. Fregat′s first burn, from 1937 to 1941 UTC, reached a 153 x 227 km x 5.2 deg parking orbit. A second, long, burn from 1949 to 1958 UTC put the stack in a 242 x 7875 km x 3.2 deg transfer orbit. After the stack coasted to apogee, burn 3 at 2119 to 2124 UTC circularized the orbit and reduced inclination to 7820 x 7840 km x 0.04 deg. O3b spacecraft FM10 and FM11 were ejected at 2128 UTC; a small further burn at 2143 UTC adjusted the Fregat orbit and spacecraft FM9 and FM12 were ejected at 2149 UTC. Further Fregat burns lowered the empty stage to a 7698 x 7836 km x 0.06 deg orbit.
