Indosat appointed Thales Alenia Space to build and launch Palapa-D satellite through a tender process in which Indosat invited several potential experienced manufacturers from domestic and international. Indosat based the appointment of Thales Alenia Space on its capability to meet Indosat's requirements and its ability to provide competitive and comprehensive communications solutions. Indosat and Thales Alenia Space have jointly selected Long March 3B as the launch vehicle for the Palapa-D satellite.

SATELLITE INFO
Optus D Series
At the end of 2003 Orbital was awarded a firm order for two GEO satellites by Sydney, Australia based Optus Networks, Pty. Then, in early 2007, Optus awarded Orbital a contract for a third satellite. Based on Orbital’s STAR platform, the satellites will provide Ku-band fixed communications and direct television broadcasting services to Australia and New Zealand.
The three satellites will initiate Optus’ D-series of satellites. The first two satellites, known as D1 and D2, will generate approximately 3.8 kilowatts of payload power to service 24 active transponders. The third satellite, D3, will generate approximately 5 kilowatts of payload power to service up to 32 active transponders.

from 183 degrees East, a West Hemi beam (covering Australia, Indonesia, the Philippines, Japan,
China, Korea and the Pacific Islands) and an East Hemi beam (providing coverage and connectivity
to the U.S., Hawaii and Polynesia).
The satellite will provide a minimum service life of 15 years.

INTELSAT 5 169°E
PanAmSat Corporation ordered its fifth satellite from Hughes Space and Communications Company in March 1995, an enhanced version of the Hughes HS 601 model designated HP for High Power. At beginning of life, it generates nearly 10 kilowatts. This version takes advantage of such advances as dual-junction gallium arsenide solar cells, new battery technology and the first commercial use of a high-efficiency xenon ion propulsion system (XIPS). These features allow the Hughes-now Boeing-601HP to accommodate payloads twice as powerful as those of regular 601 models, while still offering lifetimes as long as 15 years.
In October 2000, Hughes Space and Communications Company became Boeing Satellite Systems, Inc.
PanAmSat became HSC's first customer to launch the new model, on Aug. 28, 1997, on a Russian Proton rocket from the Baikonur Cosmodrome in Kazakhstan.
The Boeing 601 satellites are three-axis, body-stabilized models. The series was introduced in 1987 to meet anticipated requirements for high-power, multiple-payload satellites for such applications as direct-to-home television broadcasting, private business networks, and mobile communications. The spacecraft body is composed of two modules: the primary bus structure that carries all launch vehicle loads and contains the propulsion subsystem, bus electronics, and battery packs; and a honeycomb structure that houses communications equipment, electronics, and isothermal heat pipes. Reflectors, antenna feeds, and solar arrays are mounted directly to the payload module, and antenna configurations can be placed on three faces of the bus. Such a modular approach allows work to proceed in parallel on the two structures, thereby shortening the manufacturing schedule and test time.

PanAmSat Corporation ordered its fifth satellite from Hughes Space and Communications Company in March 1995, an enhanced version of the Hughes HS 601 model designated HP for High Power. At beginning of life, it generates nearly 10 kilowatts. This version takes advantage of such advances as dual-junction gallium arsenide solar cells, new battery technology and the first commercial use of a high-efficiency xenon ion propulsion system (XIPS). These features allow the Hughes-now Boeing-601HP to accommodate payloads twice as powerful as those of regular 601 models, while still offering lifetimes as long as 15 years.
In October 2000, Hughes Space and Communications Company became Boeing Satellite Systems, Inc.
PanAmSat became HSC's first customer to launch the new model, on Aug. 28, 1997, on a Russian Proton rocket from the Baikonur Cosmodrome in Kazakhstan.
The Boeing 601 satellites are three-axis, body-stabilized models. The series was introduced in 1987 to meet anticipated requirements for high-power, multiple-payload satellites for such applications as direct-to-home television broadcasting, private business networks, and mobile communications. The spacecraft body is composed of two modules: the primary bus structure that carries all launch vehicle loads and contains the propulsion subsystem, bus electronics, and battery packs; and a honeycomb structure that houses communications equipment, electronics, and isothermal heat pipes. Reflectors, antenna feeds, and solar arrays are mounted directly to the payload module, and antenna configurations can be placed on three faces of the bus. Such a modular approach allows work to proceed in parallel on the two structures, thereby shortening the manufacturing schedule and test time.

ASIASAT 4 122.2°E
Asia Satellite Telecommunications Company Ltd. (AsiaSat) ordered its AsiaSat 4 satellite from Boeing Satellite Systems (BSS), Inc., in September 2000. The satellite is a Boeing BSS-601HP or "high power" version of the body-stabilized spacecraft. AsiaSat 4 is designed to provide broadcast, telecommunications and broadband multimedia services to the Asia Pacific region, and direct-to-home broadcast services to Hong Kong, Australia , New Zealand from its orbital position of 122É East longitude.

AsiaSat 4 is designed to provide broadcast, telecommunications and broadband multimedia services to the Asia Pacific region, and direct-to-home broadcast services to Hong Kong, Australia , New Zealand from its orbital position of 122É East longitude.
AsiaSat 4 launched successfully April 11, 2003 on an Atlas-3B-SEC rocket from Cape Canaveral, Fla. The satellite will generate up to 9,600 watts using two sun-tracking four-panel solar wings covered with triple-junction gallium arsenide solar cells. AsiaSat 4 will operate in C-band and Ku-band. The satellite carries 28 active transponders with six spares in C-band, powered by 55-watt traveling-wave tube amplifiers (TWTAs), and 20 active transponders with four spares in Ku-band, powered by 140-watt TWTAs.
The C-band payload is designed to offer pan-Asian coverage, similar to AsiaSat 3S , also a 601HP model. The Ku-band payload will offer high power, and spot beams for selected areas in either the Fixed Satellite Service frequency band or in the Broadcast Satellite Service frequency band.
Type / Application:Communication
Operator:Asia Satellite Telecommunications Company
Contractors:Hughes Boeing
Equipment:28 C-band, 20 Ku-band transponders
Propulsion:R-4D-11-300, 4 XIPS-13 ion engines
Lifetime:15 years
Mass:4137 kg

PALAPA D1 113°E
PT Indosat Tbk appointed in July 2007 Thales Alenia Space to build and launch the Palapa-D satellite. Palapa-D, which launch is expected during second half 2009, will replace Palapa-C2 satellite which will expired in 2011 placed in slot 113º BT.
Based on Thales Alenia Space Spacebus-4000B3 platform, Palapa-D satellite will have larger capacity compared to Palapa-C2 satellite of which it has 24 standard C-band, 11 extended C-Band and 5 Ku-band transponders, with coverage of Indonesia, ASEAN countries, Asian countries, Middle East and Australia, New Zealand. Palapa-D satellite will have a launch mass of 4.1 tons, a payload power of 6 kW and service life time of 15 years.
