This is a list of the satellites operated by Optus, an Australian telecommunications company. The satellite communications facility is located at Belrose on Sydney's Northern Beaches. Optus' satellites are divided into 4 classes A, B, C and D. As of April 2014 it owns and operates Optus B3, Optus C1, Optus D1, Optus D2 and Optus D3. Optus A1, Optus A2, Optus A3 and Optus B1 satellites have been retired. Optus has the largest network of satellites in Australia and New Zealand.
The Anik satellites are a series of geostationary communications satellites launched for Telesat Canada for television, voice and data in Canada and other parts of the world, from 1972 through 2013. Some of the later satellites in the series remain operational in orbit, while others have been retired to a graveyard orbit. The naming of the satellite was determined by a national contest, and was won by Julie-Frances Czapla of Saint-Léonard, Québec. In Inuktitut, Anik means "brother".
The Nimiq satellites are a Canadian fleet of geostationary telecommunications satellites owned by Telesat and used by satellite television providers including Bell Satellite TV and EchoStar. 'Nimiq' is an Inuit word used for an object or a force which binds things together. A contest in 1998 was held to choose the name of these satellites. The contest drew over 36,000 entries. Sheila Rogers, a physiotherapist from Nepean, Ontario, submitted the winning name.
The National Space Research and Development Agency (NASRDA) is the national space agency of Nigeria. It is a parastatal under Federal Ministry of Innovation, Science and Technology. The agency is based in the Nigerian capital city of Abuja in the Lugbe district and has a ground receiving station, among various other sites. In the past, it has cooperated in space technology with the United Kingdom, China, Ukraine and Russia. The agency has struggled with meeting its financial plans and some of its facilities are rundown. Despite this, the space agency is one of the most advanced space agencies in Africa, boasting of four satellites and very grand ambitions. Nigeria's satellites have been praised for their high-resolution images. NASRDA is host to one of UN-SPIDER's Regional Support Offices (RSO) in Africa.
Dong Fang Hong 2 was the primary television satellite used by China during the later part of the 20th century. It was developed at the Chinese Academy of Space Technology (CAST) and had a design life 4.5 years. The first operational satellite in this group was launched into a geosynchronous orbit on 8 April 1984.
AsiaSat 1 was a Hong Kong communications satellite, which was owned, and was operated, by the Hong Kong based Asia Satellite Telecommunications Company. It was originally launched in February 1984 as Westar 6, but following a booster motor failure it was retrieved and returned to Earth in November of that year by Space Shuttle mission STS-51-A. After being sold to AsiaSat and refurbished, it was relaunched in April 1990, and positioned in geostationary orbit at a longitude of 100.5° East. It spent its operational life at 100.5° East, from where it was used to provide fixed satellite services, including broadcasting, audio and data transmission, to Asia and the Pacific Ocean.
AsiaSat 2 was a Hong Kong communications satellite, which was owned, and was initially operated, by the Hong Kong based Asia Satellite Telecommunications Company. It was positioned in geostationary orbit at a longitude of 17° East of the Greenwich Meridian, on lease to Spacecom. It spent most of its operational life at 100.5° East, from where it was used to provide fixed satellite services, including broadcasting, audio and data transmission, to Asia and the Pacific Ocean.
The PakSat-MM1 is a communications satellite, leased to the Space & Upper Atmosphere Research Commission, by the Hong Kong based Asia Satellite Telecommunications Company (AsiaSat). Originally known as AsiaSat 4, it was positioned in geostationary orbit at a longitude of 122° East of the Greenwich Meridian, but now moved to 38.2° East.
NigComSat-1 was a Nigerian communication satellite. The initial contract to build the satellite was signed in 2004. It was launched in China by Nasrda and became the third African geosynchronous communication satellite, when it was launched at 16:01 UTC on 13 May 2007, aboard a Chinese Long March 3B carrier rocket, from the Xichang Satellite Launch Centre in China. The spacecraft was operated by Nigerian Communications Satellite Ltd (NIGCOMSAT). On November 11, 2008, NigComSat-1 failed in orbit after running out of power due to an anomaly in its solar array.
Paksat-1,, was a geosynchronous and communications satellite built and owned by the Boeing Company, leased to the Space & Upper Atmosphere Research Commission (SUPARCO) and renamed Paksat-1. It was successfully put on orbit on 1 February 1996 as Palapa-C1 for Indonesia as its original customer. But, after the technical problems, the satellite was leased to SUPARCO at an orbital location of 38° East longitude in December 2002. Paksat-1 offers the C-band and Ku-band coverage in over 75 countries across Europe, Africa, Middle East, South and Central Asia. Its customers included government organizations, television broadcasters, telecommunications companies, data and broadband internet service providers.
