Azerspace-1/Africasat-1a,[4] also known as AzerSat-1 (Azerbaijani: AzərSat-1) is Azerbaijan's first satellite in space. Built by Orbital Sciences Corporation, it was launched into orbit on February 7, 2013 from Kourou in French Guiana at orbital positions 46° east.[5][6][7] The satellite was launched aboard Ariane 5. The satellite covers Europe and a significant part of Asia and Africa. It has transmission capabilities for TV, radio broadcasting and the internet.[8][9]

The satellite has an anticipated service life of 15 years.[10]

Cost

It is believed that the satellite cost of US$ 120 million and was established by Orbital Sciences Corporation.[11][12] Arianespace’s president Jean-Yves Le Gall emphasized that the weight of the satellite would be three tonnes.[13] In April 2011, Export-Import Bank of the United States has approved financing of this project as 85 percent of construction cost which will be provided to the Azerbaijani side in the form of a loan, while the remaining 15 percent will be paid by state funds.[14][15][16] The funds will be issued to Azerkosmos OJSC.[17]

Satellite specifications

The satellite has solar arrays with four panels per array, using UTJ Gallium Arsenide cells. It will be stabilized with a 3-axis stabilized, zero momentum system. It will have a liquid bi-propellant transfer orbit system, with a monopropellant (hydrazine) on-orbit system. Power will be held in two Li-Ion batteries with a capacity of >4840 W/hr.

Azersat/Africasat-1A will have a hybrid payload including both C- band and Ku-band antennae. There will be 24 active C-band transponders, using a 2.5 m × 2.7 m (8 ft 2 in × 8 ft 10 in) single shell super-elliptical deployable reflector, with a 1.4 m × 1.4 m (4 ft 7 in × 4 ft 7 in) single shell super-elliptical deck-mounted reflector. There will also be 12 active Ku-band transponders, using a 2.5 m × 2.7 m (8 ft 2 in × 8 ft 10 in) single shell super-elliptical deployable reflector.

The Ku-band transponders (11.2 GHz and 14.0 GHz) have a contour map that primarily covers Europe and Central Asia. The C-band contour map (3740 MHz and 5965 MHz) also covers Europe and Central Asia, as well as nearly all of Africa.[18][19]

Orbit

The satellite based on Orbital’s flight-proven STAR-2 platform and generates approximately five kilowatts of payload power for 36 active transponders.[20] Upon completion of in-orbit testing, operational control of the satellite was handed over to Azerbaijan’s Ministry of Communications and IT.

Operation

The satellite's operations are controlled by a state-run company, Azercosmos, operating under the Azerbaijan’s Ministry of Communications and IT.[21] Azersat/Africasat-1A is a joint venture between Azerbaijan and satellite fleet operator MEASAT Satellite Systems of Malaysia, which owns the rights to the orbital slot at 46 degrees east longitude,[18] and which will be using about 40 percent of the satellite’s total capacity. Azerbaijan uses 20 percent, with the remaining capacity to be available for other customers.[22]

As of 2014, satellite carries 13 radio stations and 128 television channels, mostly free to air, in addition to its services to the government.[23]

Launch

The Azersat/Africasat-1A has had a planned launch for mid-2012 by Europe’s Arianespace launch consortium under a separate contract valued at $93 million. Azerbaijan and its bank consortium, led by BNP Paribas, has reportedly been negotiating with France’s Coface export-credit agency to back the launch-services contract. On 23 November 2011, it was confirmed the launch would proceed within the expected 2012 timetable.[22][24]

Future plans

The launch of its own satellite on orbit became Azerbaijan's first action in realizing prospective projects to turn itself into a country with a space industry.[25][26] In addition, deputy director of Azerbaijan National Aerospace Agency, Tofig Suleymanov in April 2011 hinted that Azerbaijan may launch second artificial satellite to study the Earth's interior and atmosphere in 2014.[27][28][29] On 26 November 2011, Head of Azercosmos, Rashad Nabiyev has reported that launch of the second satellite expected to start at 2015.[30][31]
