ILS Proton to Launch Astra 2G
ASTRA 2G is the third spacecraft of a three satellite investment programme (ASTRA 2E, 2F and 2G) that SES contracted with Airbus Defence and Space in order to provide replacement as well as incremental satellite capacity in the orbital arc of 28.2/28.5 degrees East. ASTRA 2G carries 62 Ku-band transponders as well as 4 Ka-band transponders. The different beams provide coverage over the UK and Ireland, Europe and West Africa.

Satellite Use: ASTRA 2G is the third spacecraft of a three satellite investment program (ASTRA 2E, 2F, and 2G) that SES contracted with Airbus Defence and Space in order to provide replacement as well as incremental satellite capacity in the orbital arc of 28.2/28.5 degrees East. ASTRA 2G carries 62 Ku-band transponders as well as 4 Ka-band transponders. The different beams provide wide coverage over the UK and Ireland, Europe and West Africa.
The ASTRA 2G satellite will also support SATMED, an e-health platform conceived by SES and supported by the Luxembourg Government and the Ministry for Cooperation and Humanitarian Action is a satellite based communication solution aimed to improve public health in emerging and developing countries.

__Anticipated service life: 15 years
Mission Profile: The Proton M launch vehicle, utilizing a 5-burn Breeze M mission design, will lift off from Pad 39 at Baikonur Cosmodrome, Kazakhstan, with the ASTRA 2G satellite on board. The first three stages of the Proton will use a standard ascent profile to place the orbital unit (Breeze M Upper Stage and the ASTRA 2G satellite) into a sub-orbital trajectory. From this point in the mission, the Breeze M will perform planned mission manoeuvres to advance the orbital unit first to a circular parking orbit, then to an intermediate orbit, followed by a transfer orbit, and finally to a geosynchronous transfer orbit. Separation of the ASTRA 2G satellite is scheduled to occur approximately 9 hours, 12 minutes after liftoff.
Target Orbit Perigee: 4,163 km
at Separation: Apogee: 35,736 km
Inclination: 23.0 degrees
Spacecraft Separation: Approximately 9 hours, 12 minutes after liftoff
