On December 26, 2017, at 22:00 Moscow Time, the integrated launch vehicle Zenit-3SLBF carrying Angosat spacecraft (SC) was launched from the launch pad of Area 45 of the Baikonur cosmodrome.

The upper stage Fregat-SB carrying Angosat SC separated from the launch vehicle on time.

Angosat spacecraft (SC) was made at RSC Energia under a contract with the Ministry of Telecommunications and Information Technologies of the Republic of Angola and is built around a new satellite bus constructed out of Russian-made components.

The Angosat SC project used a number of innovative solutions, which made it possible to build a fairly powerful SC with a mass that is relatively low (2647 kg) for the satellites of this class. The electric propulsion system installed on the Angosat SC enables a slow ascent of the spacecraft to its final orbit (if need be) and corrections of its orbital position.

Angosat is a spacecraft made by RSC Energia in the interests of the Republic of Angola to provide broadcast coverage in C- and Ku-bands over the territory of the Republic of Angola, as well as over the territory of the entire African continent. The Angosat project calls for constructing a communications satellite with a transponder, launching it into the geostationary orbit and building a round infrastructure for communications and TV broadcasting. Also taking part in the implementation of the project are enterprises included in the State Corporation Roscosmos.
