ARSAT-1
ARSAT-1 is a geostationary communications satellite operated by AR-SAT and built by the Argentine company INVAP. ARSAT-1 was launched into orbit on October 16, 2014, from French Guiana alongside Intelsat-30 satellite using an Ariane 5 rocket. It is expected to be located at 72° West longitude geostationary slot. ARSAT-1 is the first geostationary satellite built in Latin America. Total cost of the satellite is 270 million US dollars.
ARSAT-1 carries a total of 24 IEEE Ku band (NATO J-band) transponders. Twelve will be operating at 36 MHz, eight at 54 MHz and four at 72 MHz, for a total bandwidth of 1152 MHz. It will offer a wide range of telecommunications, data transmission, telephone and television services mainly across all of Argentina, Chile, Uruguay and Paraguay including direct broadcast TV in the ISDB-S standard.
The ARSAT-1 is the first flight model of the ARSAT-3K satellite bus developed by INVAP for ARSAT S.A. It is a small (around 3 t (3.3 tons) at launch) platform with a 350 kg (770 lb) maximum payload mass and 3.5 kW of payload power consumption at the satellite end of life. It uses an integrated chemical propulsion system supplied by EADS Astrium for both orbit raising and station keeping.
The satellite uses a Ku band communication payload which was supplied by Thales Alenia Space. It is a composed of twelve 36 MHz transponders, eight of 54 MHz and four of 72 MHz, for a total bandwidth of 1152 MHz or 32 TPE.
On April 26, 2006, the Argentine Federal Law 26.092 created ARSAT S.A. By section 8 of said law the company is given the right to exploit the 81° West orbital slot. By Section 4 of the company's constitution, it is mandated to build in the country and operate a communication satellite. By the Decree 626/2007 of the National Communications Commission published on May 30, 2007, the rights to the 71.8° West orbital slot is transferred from Nahuelsat to ARSAT S.A. On August 28, 2008, ARSAT S.A. signs the order for the ARSAT-1 satellite with INVAP. On December 10, 2008, INVAP and ARSAT S.A. successfully performed the Preliminary Design Review for the satellite design.
On September 8, 2009, ARSAT announced that Thales Alenia Space had been selected to supply the communication payload of the satellite and that Astrium would supply the hardware for the onboard computer, the central cylinder and some of the propulsion subsystems. On September 8, 2010, Honeywell announces that it had received a $2.4 million order to supply the reaction wheels and the MIMU for the satellite.
In April 2010, ARSAT announced that Arianespace would launch ARSAT-1 from the Guiana Space Centre. On February 21, 2013, the mating of the ARSAT-3K satellite bus and the payload module was successfully completed.
In October 2013 the environmental testing campaign was started with the month long thermal vacuum chamber tests. It went through a series of mass properties measures before going into the vibration testing in January. On February 10, 2014, ARSAT-1 successfully passed the vibration environment simulation on the CEATSA shaker. It then performed a series of sound environment simulations that assured that the satellite would survive the launch environment.
