APSTAR 2R (e. hemi. list) Space Systems/Loral’s (SS/L) APSTAR-IIR is one of the most powerful spacecraft in Asia-Pacific s e rvice. It was launched in China in 1997 by APT Satellite Company, Ltd. The satellite allows APT to offer regional voice, video, and data services to an area large enough to link Europe, Russia, the Middle East, Africa, and the Asia-Pacific region into a broad telecommunications network. APSTAR IIR’s powerful payloads makes it possible to establish an inexpensive direct-to-home satellite-based telecommunications network in China through the use of small diameter receiving dishes. SS/L expects that major U.S. and international programmers will provide programming for such a service. The geostationary satellite provides coverage to an area ranging from Central Europe to Japan, and from northern Russia to South Africa and Australia with one C-band beam with 28 traveling wave tubes rated at 60 watts each. China is being served with APSTAR-IIR’s two Ku-band beams, with a total of 16 traveling wave tubes at 110 watts each. The satellite boasts total on-board transmitter power of 3440 watts. APT Satellite Company, Ltd., is a major international satellite operator in Asia, and is owned by a consortium of China state-owned companies and commercial firms in Taiwan, Thailand, Macau, and Singapore. The new spacecraft replaces APSTAR-2, manufactured by another company, which was lost in a launch accident in early l995. The APSTAR-IIR high-power satellite is based on SS/L’s three-axis, body-stabilized FS-1300 bus, whose modular design has proven its worth during some 275 years of cumulative on-orbit service, nearly 45% of the total of 630 plus years amassed by SS/L satellites to date. APSTAR-IIR was launched aboard a Long March 3B. The FS-1300 buses achieve long useful orbital life - in this case 15 years - through use of a bipropellant propulsion system and a momentum-bias system for excellent stationkeeping and orbital stability. Solar arrays and nickel-hydrogen batteries provide uninterrupted electrical power. |

INTELSAT VII/VIIA SERIES (list 701,
702, 703,
704, 705,
706A, 707A,
709) The eight high-powered Space Systems/Loral (SS/L) spacecraft of the INTELSAT VII/VIIA program, which provide global dissemination of voice, video, and data transmission services, have been launched and are in orbit. The program, conducted for the more than 140 member nations of the International Telecommunications Satellite Organization (INTELSAT), began with the first launch of the series in October, 1993. This orbital network consists of highly reliable communications satellites, positioned over the Atlantic, Indian, and Pacific Ocean regions. That network is designed to provide flexible interconnection between coverage areas that can be changed to respond to communications needs that develop and change from hour-to-hour and day-to-day. The geostationary INTELSAT VII and VIIA satellites are designed to provide the radio frequency power, capacity, and coverage to satisfy the burgeoning global appetite for digital services, smaller earth stations, and specialized INTELSAT communications services. The INTELSAT VII/VIIA communications payload architecture evolved from SS/L’s INTELSAT V series and consists of two independent communications subsystems, which can be cross-strapped and operate at C-band (4/6 GHz) and Ku-band (11/14 GHz). Total end of life solar array transmitter power generated by an INTELSAT VII is 3600 watts, while an INTELSAT VIIA generates 4800 watts. The INTELSAT VII/VIIA spacecraft are based on SS/L’s three-axis, body-stabilized FS-1300 bus, whose modular design has proven its worth during some 275 years of cumulative on-orbit service, close to 45% of the total of 630 plus years amassed by SS/L satellites to date. The INTELSAT VIIA designation identifies the three satellites that were enlarged and fitted with additional communications capacity and power. Four additional, more powerful Ku-band transponders, each with up to 73-watt TWTAs, and a fourth solar-array panel provided the added capacity. INTELSAT VII/VIIA spacecraft were launched on Ariane 4 and Atlas Centaur IIAS vehicles. Nine INTELSAT VII/VIIA’s were actually built, but one was destroyed in a failed launch attempt. SS/L’s team members for the successful INTELSAT V and VII/VIIA programs were Aerospatiale and Alcatel Telcom of France, Alenia, Italy, and Mitsubishi Electric Corporation (MEICO) and NEC of Japan. The FS-1300 buses achieve long useful orbital life - in this case 16.5 years - through use of a bipropellant propulsion system and a momentum-bias system for excellent stationkeeping and orbital stability. Solar arrays and nickel-hydrogen batteries provide uninterrupted electrical power. |

MABUHAY (AGILA 2) (e.
hemi. list) Space Systems/Loral’s (SS/L) Mabuhay is one of the most powerful telecommunications satellite in service in the Asia-Pacific region. It was delivered on-orbit in 1997. The new satellite is a prime example of SS/L’s dominance in the emerging domestic and international broadcast satellite market. Designed, built, and launched by SS/L for Mabuhay Philippines Satellite Corporation, Mabuhay delivers broadcast television, telephone, and data services to an area that covers Southeast Asia, from the Philippines to Hawaii, to India, Pakistan, and Bangladesh, and to Vietnam and China. A single Mabuhay satellite is able to transmit more than 190 channels of high-fidelity digital programming to cable companies and home satellite dishes, along with the capability to handle more than 50,000 simultaneous two-way telephone conversations. Mabuhay features the largest number of active transponders of any satellite in the region. It contains 30 C-band transponders at 27 watts and 24 Ku-band transponders at 110 watts, combinable to 12 high-power 220-watt transponders. Total dc power at End of Life (EOL) will be more than 8200 watts. The combination provides a power-to-mass ratio of 5-to-1, making Mabuhay one of the most efficient satellites in the industry. As part of the contract, SS/L procured the launch vehicle, built a satellite control ground station in Subic Bay in the Philippines, and provided trainingfor Mabuhay personnel who operate the satellite. The spacecraft was launched on a Long March 3B The Mabuhay spacecraft is based on SS/L’s three-axis, body-stabilized FS-1300 bus, whose modular design has proven its worth during some 275 years of cumulative on-orbit service, close to 45% of the total of 630 plus years amassed by SS/L satellites to date. The FS-1300 buses achieve long useful orbital life -in this case more than 12 years - through use of a bipropellant propulsion system and a momentum-bias system for excellent stationkeeping and orbital stability. Solar arrays and nickel-hydrogen batteries provide uninterrupted electrical power. |
