SES Americom was a major commercial satellite operator of North American geosynchronous satellites based in the United States. The company started as RCA Americom in 1975 before being bought by General Electric in 1986 and then later acquired by SES S.A. in 2001. In September 2009, SES Americom and SES New Skies merged into SES World Skies.
Boeing 702 is a communication satellite bus family designed and manufactured by the Boeing Satellite Development Center, and flown from the late-1990s into the 2020s. It covers satellites massing from 1,500 kg (3,300 lb) to 6,100 kg (13,400 lb) with power outputs from 3 to 18 kW and can carry up to approximately 100 high-power transponders.
JSAT Corporation (JSAT) was the first private Japanese satellite operator, which owned the JSAT satellites, as well as operated and partially owned the N-Star with NTT DoCoMo. Its origins can be traced to the funding of Japan Communications Satellite Company (JCSAT) and Satellite Japan Corporation in 1985. Both companies merged into Japan Satellite Systems Inc. in 1993. In 2000 the company was renamed as JSAT Corporation and was listed in the First Section of the Tokyo Stock Exchange. On September 1, 2008, the company was merged into the SKY Perfect JSAT Group.
Horizons Satellite is a joint venture between Intelsat and SKY Perfect JSAT Group. Originally formed in 2001, pursuant to a memorandum of understanding between JSAT Corporation and PanAmSat for the launch of Horizons-1, it was renewed for Horizons-2. JSAT later merged into the SKY Perfect JSAT Group and PanAmSat was acquired by Intelsat, but the companies continued with the relationship, with the order for Horizons-3e. Both companies also launched a joint satellite, Intelsat 15/JCSAT-85, but instead of the equal share agreement of this joint venture, JSAT owns a specific payload of 5 transponders out of the 22 Ku band transponders of the spacecraft.
Intelsat 15, also known as IS-15, is a communications satellite owned by Intelsat. Intelsat 15 was built by Orbital Sciences Corporation, on a Star-2.4. It is located at 85° E longitude on the geostationary orbit. It was launched from Baikonur Cosmodrome to a geosynchronous transfer orbit on 30 November 2009 by a Zenit-3SLB launch vehicle. It has 22 active Ku band transponders, plus eight spares. Five of those transponders are owned and operated by SKY Perfect JSAT Group under the name JCSAT-85.
Intelsat 27 was an American communications satellite which was to have been operated by Intelsat. Intended as a replacement for Intelsat 805, it was destroyed after the rocket carrying it to orbit fell into the Pacific Ocean 56 seconds after launch.
Horizons-3e, also known as IS-H3e, is a high throughput geostationary communications satellite ordered by Horizons Satellite, a joint venture of Intelsat and SKY Perfect JSAT Group. The spacecraft is designed and manufactured by Boeing on the Boeing-702MP platform.
The JSAT constellation is a communication and broadcasting satellite constellation formerly operated by JSAT Corporation and currently by SKY Perfect JSAT Group. It has become the most important commercial constellation in Japan, and fifth in the world. It has practically amalgamated all private satellite operators in Japan, with only B-SAT left as a local competitor.
JCSAT-4 was known as JCSAT-R until it was sold to INTELSAT in 2009. It is a geostationary communications satellite designed and manufactured by Hughes on the HS-601 satellite bus. It was originally ordered by JSAT Corporation, which later merged into the SKY Perfect JSAT Group. It has a mixed Ku-band and C-band payload and was used as an on orbit spare.
Intelsat 29e, also known as IS-29e was a high throughput (HTS) geostationary communications satellite designed and manufactured by Boeing Satellite Development Center on the BSS 702MP satellite bus. It is the first satellite of the EpicNG service, and covers North America and Latin America from the 50° West longitude, where it replaced Intelsat 1R. It also replaced Intelsat 805 which was moved from 56.5° West to 169° East. It has a mixed C-band, Ku-band and Ka-band payload with all bands featuring wide and the Ku- also featuring spot beams.
Intelsat VA F-13 or Intelsat 513, then named 'NSS-513', was a communications satellite operated by Intelsat and which was later sold to New Satellite Skies. Launched in 1988, it was the thirteenth of fifteen Intelsat V satellites to be launched. The Intelsat V series was constructed by Ford Aerospace, based on the Intelsat VA satellite bus. Intelsat VA F-13 was part of an advanced series of satellites designed to provide greater telecommunications capacity for Intelsat's global network.
NSS-703 is a geostationary communication satellite that was built by Space Systems/Loral (SSL). It is located in the orbital position of 29.5 degrees east longitude and it is currently in an inclined orbit. The same is owned by Intelsat and after sold to SES World Skies on November 30, 1998. The satellite was based on the LS-1300 platform and its estimated useful life was 15 years.
Intelsat 704 is a geostationary communication satellite that was built by Space Systems/Loral (SSL). It is located in the orbital position of 29.5 degrees east longitude and it is currently in an inclined orbit. The same is owned by Intelsat and after sold to SES World Skies on November 30, 1998. The satellite was based on the LS-1300 platform and its estimated useful life was 15 years.
Intelsat 709 is a geostationary Communications satellite that was built by Space Systems/Loral (SSL). It is located in the orbital position of 47.5° west longitude. The satellite is owned by Intelsat. The satellite was based on the LS-1300 platform and its estimated useful life was 15 years.
Intelsat 802 was a communications satellite operated by Intelsat. Launched in 1997 it was operated in geostationary orbit at a longitude of 174 degrees west for around fourteen years.
NSS-5 is a communications satellite operated by Intelsat and after by SES World Skies. Launched in 1997 it was operated in geostationary orbit at a longitude of 50.5 degrees east for around 14 years.
Intelsat 804 was a communications satellite operated by Intelsat. Launched in 1997 it was operated in geostationary orbit at a longitude of 44 degrees east for around 8 years.
NSS-806, before Intelsat 806, is a communications satellite originally operated by Intelsat. Launched in 1998 it was operated in geostationary orbit at a longitude of 47 degrees west for around 15 years. It is currently located in the orbital position of 47.5 degrees west longitude, was initially operated by Intelsat, orbited at 40.5 degrees west, and was purchased by SES World Skies.
