From its equatorial launch site at 154 degrees West Longitude, a Zenit-3SL launch vehicle inserted the 3,038 kg (6,697 lb) SICRAL 1B spacecraft to geosynchronous transfer orbit, on its way to its final orbital location at 11.8 degrees East Longitude. The first stage of the vehicle separated two-and-a-half minutes after liftoff and the protective payload fairing was jettisoned a minute later. After operating for six minutes, the second stage separated from the Block DM upper stage. The Block DM operated for an eight-and-a-half minute burn. Following a coast period of one hour and 18 minutes, the Block DM burned a second time for three minutes. After the second burn, and another 10-minute coast, the spacecraft separated from the upper stage over central Africa. A ground station at Telespazio's Fucino Space Centre in Italy acquired the first signals from the SICRAL 1B satellite and confirmed its operational status.
