Intelsat VII |
Intelsat 701 (also known as IS-701 and Intelsat 7-F1) 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. The satellite was based on the LS-1300 platform and its estimated useful life was 15 years.
Communication is the act of conveying meanings from one entity or group to another through the use of mutually understood signs, symbols, and semiotic rules.
In the context of spaceflight, a satellite is an artificial object which has been intentionally placed into orbit. Such objects are sometimes called artificial satellites to distinguish them from natural satellites such as Earth's Moon.
A satellite is said to occupy an inclined orbit around Earth if the orbit exhibits an angle other than 0° to the equatorial plane. This angle is called the orbit's inclination. A planet is said to have an inclined orbit around the Sun if it has an angle other than 0° to the ecliptic plane.
The satellite was successfully launched into space on October 22, 1993, at 06:46:00 UTC, using an Ariane 44L vehicle from the Guiana Space Center in French Guiana. It had a launch mass of 3,642 kg.
The Ariane 4 was an expendable launch system, designed by the Centre national d'études spatiales (CNES) while being manufactured by ArianeGroup and marketed by Arianespace. Since its first flight on 15 June 1988 until the final flight, which was performed on 15 February 2003, it attained 113 successful launches out of 116 launches to have been conducted.
French Guiana is an overseas department and region of France, on the north Atlantic coast of South America in the Guyanas. It borders Brazil to the east and south and Suriname to the west. Since 1981, when Belize became independent, French Guiana has been the only territory of the mainland Americas that is still part of a European country.
The Intelsat 701 is equipped with 26 transponders in C band and 10 in Ku band to provide broadcasting, business-to-home services, telecommunications, VSATnetworks.
The C band is a designation by the Institute of Electrical and Electronics Engineers (IEEE) for a portion of the electromagnetic spectrum in the microwave range of frequencies ranging from 4.0 to 8.0 gigahertz (GHz); however, this definition is the one used by radar manufacturers and users, not necessarily by microwave radio telecommunications users. The C band is used for many satellite communications transmissions, some Wi-Fi devices, some cordless telephones as well as some surveillance and weather radar systems.
The Ku band is the portion of the electromagnetic spectrum in the microwave range of frequencies from 12 to 18 gigahertz (GHz). The symbol is short for "K-under", because it is the lower part of the original NATO K band, which was split into three bands because of the presence of the atmospheric water vapor resonance peak at 22.24 GHz, (1.35 cm) which made the center unusable for long range transmission. In radar applications, it ranges from 12-18 GHz according to the formal definition of radar frequency band nomenclature in IEEE Standard 521-2002.
Intelsat 24, previously Amos-1, is a commercial communication satellite which is operated by Intelsat. It was previously operated by Spacecom as Amos-1, and formed part of the AMOS series of satellites. It was the first Israeli civilian communications satellite, and was initially positioned at 4° West longitude in geostationary orbit. It has since been moved to 47.3 degrees East.
Horizons-2 is a Ku band communications satellite owned by Horizons Satellite, a joint venture between SKY Perfect JSAT Group and Intelsat. Its orbital slot is located at 74° west longitude.

INSAT-2E is an Indian geostationary communications and weather satellite which is operated by the Indian National Satellite System. It is positioned in geostationary orbit at a longitude of 83° East, from where it is used to provide communications services to Asia and Australia. It also carries two meteorological instruments; the Very High Resolution Radiometer, and a CCD camera capable of returning images with a resolution of one kilometre.
Yahsat 1A is a communications satellite constructed by EADS Astrium and Thales Alenia Space for Al Yah Satellite Communications Company (Yahsat). It was launched in April 2011 from Arianespace's Guiana Space Centre in Kourou French Guiana in a dual payload launch with Intelsat New Dawn atop an Ariane 5 ECA rocket. Yahsat Y1A is based on the Eurostar E3000 satellite bus and had a launch mass of about 6000 kg. It is intended to provide Ku, Ka and C-band communications to the Middle East, Africa, Europe and Southwest Asia. It is in geosynchronous orbit at fifty three degrees East.
Intelsat 33e, also known as IS-33e, is a high throughput geostationary communications satellite operated by Intelsat and designed and manufactured by Boeing on the BSS-702MP platform. It is the second satellite of the EpicNG service, and will cover Europe, Africa and most of Asia from the 60°East longitude, where it is expected to replace Intelsat 904. It has a mixed C band, Ku band and Ka band payload with all bands featuring wide and C and Ku also featuring spot beams.
Intelsat 29e, also known as IS-29e is a high throughput geostationary communications satellite designed and manufactured by Boeing on the BSS-702MP platform. It is the first satellite of the EpicNG service, and covers CONUS, Latin America and North America from the 50° West longitude, where it is 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.
