Boeing 702HP Fleet



Satellite operators have responded enthusiastically to the vastly increased capabilities represented by the Boeing 702. Boeing announced the innovative satellite series in October 1995, and in 2009 introduced a mid-ranged version, the 702MP for "mid-power." At that time the legacy Boeing 702, which has continuously evolved, was designated the Boeing 702HP for "high-power." Evolved from the popular, proven 601 and 601HP (high-power) spacecraft, the body-stabilized Boeing 702 is the world leader in capacity, performance and cost-efficiency.

The first Boeing 702HP satellite was launched in 1999. The satellite can carry more than 100 high-power transponders, and deliver any communications frequencies that customers request.

The Boeing 702 design is directly responsive to what customers said they wanted in a communications satellite, beginning with lower cost and including the high reliability for which the company is renowned. For maximum customer value and producibility at minimum total cost, the Boeing 702 offers a broad spectrum of modularity. A primary example is payload/bus integration. After the payload is tailored to customer specifications, the payload module mounts to the common bus module at only four locations and with only six electrical connectors. This design simplicity confers major advantages. First, nonrecurring program costs are reduced, because the bus does not need to be changed for every payload, and payloads can be freely tailored without affecting the bus. Second, the design permits significantly faster parallel bus and payload processing. This leads to the third advantage: a short production schedule.

Further efficiency derives from the 702's advanced xenon ion propulsion system (XIPS), which was pioneered by Boeing. XIPS is 10 times more efficient than conventional liquid fuel systems. Four 25-cm thrusters provide economical stationkeeping, needing only 5 kg of fuel per year - a fraction of what bipropellant or arcjet systems consume. Using XIPS for final orbit insertion conserves even more mass as compared to using an on-board liquid apogee engine. Customers can apply the weight savings to substantially increase the revenue-generating payload at small marginal cost, to prolong service life, or to change to a less expensive launch vehicle (when cost is based on satellite mass).

For even more versatility, the Boeing 702HP also incorporates a bipropellant propulsion system, which can lift the satellite into final orbit after separation from the launch vehicle.

Innovation extends to the Boeing 702HP power systems as well. The Boeing 702 offers a range of power up to 18 kW. Dual and triple-junction gallium arsenide solar cells enable such high power levels. Spectrolab, Inc. a Boeing subsidiary, developed the cells.

The Boeing 702HP separates the bus and payload thermal environments and substantially enlarged the heat radiators to achieve a cooler, more stable thermal environment for both bus and payload. This increases unit reliability over service life. Deployable radiators use flexible heat pipes, which increase packageable radiator area. Further thermal control occurs through passive primary rejection via heat pipes.

The baseline Boeing 702 is compatible with several launch vehicles. These include the Delta IV, Atlas V, Ariane 5, Proton, and Sea Launch.

In 1997, Boeing, received a nearly $1 billion contract for a system consisting of two 702HP satellites that will serve the provide mobile telephone service to the Middle East, North and Central Africa, Europe, Central Asia and the Indian subcontinent. It is the largest satellite communications project in the region and serves nearly 1.8 billion people. The first Thuraya satellite was launched in October 2000. Thuraya-2 was launched in June 2003.

In 2006, Boeing received a second major contract from SkyTerra LP to provide two Boeing 702HP satellites, with an option for a third. The satellites will be used to create the world's first commercial wireless world's first commercial wireless communications service, using both space and terrestrial elements. The SkyTerra-1 and SkyTerra-2 satellites will serve Canada; the United States, including Alaska, Hawaii and Puerto Rico; the Virgin Islands; Mexico; and the Caribbean Basin.

The Boeing 702HP geomobile satellite system features a 12.25-meter deployable antenna, and onboard digital signal processing and beamforming. It is a mobile-communications-supporting satellite system that integrates a Boeing geosynchronous-orbit satellite with a ground segment and a user terminal segment.

Anik F

Telesat Canada, Gloucester, Ontario

Telesat is Canada's national satellite communications company. "Anik" means "little brother" in the Inuit language. Boeing built Telesat's first satellites, the Anik A series, more than 25 years ago. The Anik F series is Telesat's newest generation, and sixth series of satellites.

Anik F1 was ordered in March 1998, and is a Boeing 702 model. The satellite carries 84 active transponders: 36 in C-band and 48 in Ku-band. The spacecraft will provide general telecommunications services for North and South America. The satellite was designed for an end-of-life power of 16 kW. Anik F1 was launched in late 2000 on an Ariane 4 rocket.

Telesat Canada ordered another Boeing 702, Anik F2, in April 2000. The satellite provides fixed satellite service, including Internet access, and Ka-band multimedia services across North America. Anik F2 operates with a total of 114 transponders: 50 in Ka-band, 40 in Ku-band and 24 in C-band. The satellite carries the flight-proven xenon ion propulsion system for all on-orbit maneuvering. The spacecraft is designed for an end-of-life power of 16 kW. Anik F2 was launched in 2004 on an Ariane 5.

Galaxy and PAS

PanAmSat Corporation, United States

PanAmSat Corporation of Wilton, Conn., was the first customer for the Boeing 702, having ordered three: Galaxy XI, Galaxy IIIC, and PAS-1R. Galaxy XI was the first Boeing 702 satellite. It was ordered in May 1997 and was successfully launched in December 1999 on an Ariane 4 rocket from Kourou, French Guiana. Galaxy XI has a payload of 64 active transponders; 24 operate in C-band and 40 operate in Ku-band. The spacecraft was designed for an end-of-life power of more than 10 kW. The satellite provides service to North America and Brazil.

Galaxy IIIC was ordered in August 1997 and was launched on June 15, 2002 by Sea Launch. The satellite serves North, South and Central America with a total of 77 transponders; 24 in C-band and 53 in Ku-band. The spacecraft was designed for an end-of-life power of 15 kW.

PAS-1R was also ordered in August 1997. The satellite carries 72 active transponders: 36 in C-band and 36 in Ku-band. That is three times the capacity of PAS-1, the spacecraft it replaced. PAS-1R designed for an end-of-life power of more than 14 kW. The satellite provides coverage to four continents from its slot over the Atlantic Ocean. PAS-1R was launched in 2000 on board an Ariane 5 rocket.


Boeing is building four 702HP spacecraft to provide new Ka-band global and high-capacity satellite services to Inmarsat, the leading provider of global mobile satellite communications services. Leveraging Boeing's extensive expertise in Ka-band satellite communications systems, the new satellites will join Inmarsat's fleet of geostationary satellites that provide a wide range of voice and data services through an established global network of distributors and service providers. The Boeing satellites will provide Inmarsat with the ability to adapt to shifting subscriber usage patterns of high data rates, specialized applications and evolving demographics over a projected 15-year lifetime. The first Inmarsat-5 satellite was launched on December 8, 2013, and the second on February 1, 2015. In a separate arrangement, Boeing has also entered into a distribution partnership with Inmarsat to provide L- and Ka-band capacity services to government and commercial users.


In 2010, Secretaria de Comunicaciones y Transportes (SCT) de México ordered an end-to-end turnkey satellite communications system that will become Mexico's next-generation telecommunications system. Boeing will design and deliver a complete system consisting of: two Boeing 702HP geomobile satellites; a satellite from Orbital Sciences Corporation for fixed satellite services; two ground stations in México, with a spacecraft operations center for network management and operation; and ground-based beam-forming and communications network equipment. Boeing also will deliver reference user terminals, which enable the end users of MEXSAT to test and validate the system. The MEXSAT system will relay civil communications in urban and remote areas throughout the country, providing mobile, voice and data services. The satellites will operate over México and its patrimonial seas, including the Gulf of Mexico and the Pacific Ocean.


New Skies Satellites N.V., The Hague

NSS-8 was the first Boeing satellite to be procured by New Skies, an independent global satellite operator that was formed through the partial privatization of INTELSAT. The spacecraft was to carry 56 active C-band and 36 active Ku-band high power transponders, making it one of the largest and highest power satellites in the region. Four 25-cm XIPS thrusters would have performed orbit raising and stationkeeping duties. Advanced triple-junction gallium arsenide solar panels built by Spectrolab were designed to deliver 17.6 kilowatts of total spacecraft power at end of life.

NSS-8 was to be stationed at 57 degrees East longitude. The spacecraft's 27 beams would have created nine footprints that would blanket Europe, Asia, India, the Middle East, Africa, Australia, and the Indian Ocean. Extensive beam-to-beam interconnectivity built into NSS-8's design would have allowed New Skies to offer flexible solutions to customer requirements and respond to market conditions over the spacecraft's life.

The NSS-8 contract includes options for up to two follow-on spacecraft. Sea Launch was selected as the launch provider under this delivery-in-orbit contract. NSS-8 was launched in 2007 but lost due to a booster failure.


In 2006, Boeing received a major contract from LightSquared (formerly called SkyTerra LP) to provide two Boeing 702HP satellites designed for geomobile services, four uplink gateway sites, and ground-based beam-forming equipment. The satellites will use both space and terrestrial elements to deliver integrated satellite-cellular communications with wireless services anytime and anywhere throughout the United States and Canada.
