Soyuz-2.1B • Galileo-13 & 14

Galileo Navigation System is still under development, but after strong expansion of Chinese Beidou navigation system in 2015, European Commission decided to intensify process of extending constellation of FOC (Full Operational Capability) satellites. Two additional satellites made by OHB will be launched this year by Arianespace on atop of Soyuz-2.1B, what will give total number of six new Galileo satellites launched in 2016. Satellites named as FOC FM10 and FOC FM11 were designed by German Company OHB (bus) and Surrey Satellite Technology (payload). Satellites will be placed on altitude of 23,616 km with inclination of 56°. Weight of each satellite is 733 kg, power is provided by two deployable solar arrays and onboard battery. Operational life is, according to OHB, over twelve years.

Arianespace is going to use during this mission Soyuz-2.1B (Soyuz-STB rocket). It is version of Soyuz-2 modified with RD-0124 engine in second stage with 297.9 kN of thrust. Four boosters are still powered by one RD-107 engine each one with thrust at 838.5 kN. First stage is equipped with one RD-108A engine with thrust at 792.5 kN. Upper stage is Fregat, powered with single S5.92 engine providing thrust at 19.85 kN. First launch from Guiana Space Center was performed with first two In-Orbit Validation Galileo satellites on 21 October 2011.
