Palapa History

The name Palapa also alludes to "Sumpah Palapa" the oath taken by Gajah Mada, a 14th century Prime Minister of the Javanese Majapahit Empire described in the Pararaton (Book of Kings). Gajah Mada swore that he would not taste any spice, as long as he had not succeeded in unifying Nusantara (the Indonesian archipelago). By referring to this ancient oath of unification, the Palapa satellite series was also identified as the modern means to unify Indonesia.

As the first developing country to operate its own domestic satellite system in the mid seventies, Indonesia has consistently taken the steps necessary for developing its existing geostationary satellite system for multiple services, safeguarding its global orbital allocation on an equitable first come first served basis, and embracing emerging satellite communication systems (including non-geostationary ones) expected to yet emerge from their lingering stage.

The program was started in February 1975, when the government of Indonesia awarded the contract for two satellites to Boeing. The name Palapa was chosen by president Suharto and means 'fruits of labor'.

The purpose of the system was to unify the telecommunications of the nation. Many years of operation have shown that satellite technology is the best solution for improving telecommunications in Indonesia. The system was started with 2 (two) satellites, each with 12 transponders (for a total of 24), and 40 earth stations.

Now the system has 3 (three) satellites, each with 24 transponders (for a total of 72 transponders), and thousands of earth stations. The services have been extended to satisfy the requirements of the region as well as the original objectives. The use of satellite transponders in the region is increasing rapidly. In the next ten years, opportunities in the satellite communications business will become even more attractive. The next generation Palapa-C will incorporate improvements in capacity, quality, and coverage. The new frequency bands (ku- and Extended-C Band) will be used to meet the new transponder.

 

Application

The generation of Palapa Satellite had been launched to fulfil the communication line in Indonesia that day by day keeps on increasing. Palapa Satellite becomes foundation continually for communication system in this biggest archipelago country. To make this satellite keep on working longer, high quality is needed. The type of microelectronic technology in this satellite determines the work of Palapa to run its task.

One of the applications is news broadcasting by digital satellite (DSNG). This technology has been developed for five years so that news in voice and video form are able to be broadcasted from one place to another. The development of technology is affected by the advance of satellite. To use DSNG application, TV broadcaster must rent minimum 9 MHz to delay video program or audio stereo with notification for a long term using.

For Broadcasting Satellite Services, Indonesia registered the connection line in the early 1990s to ITU. IndoStar-1 is a Broadcasting Satellite Service (BSS) system that has been set up and has run operationally since 1997.

Series A

Two identical satellites were built by Hughes (now Boeing Satellite Systems). Each of the HS-333 weighted 574 kg.

Palapa A2 March 3, 1977 Cape Canaveral, Pad LC-17A Delta-2914

 

 

Series B

Altogether four satellites of the second series were built. They were all of the type Hughes HS-376. When the launch of Palapa B2 failed, a third satellite was ordered. Originally named Palapa B3 and scheduled for STS-61-H, it was finally launched as Palapa B2P. Meanwhile Palapa B2 was retrieved by STS-51-A, refurbished and relaunched later as Palapa B2R.

Palapa B1 June 6, 1983 STS-7
Palapa B2 February 3, 1984 STS-41-B
Palapa B2P March 20, 1987 Cape Canaveral, Pad LC-17B Delta-3920 PAM-D
Palapa B2R April 13, 1990 Cape Canaveral, Pad LC-17B Delta-6925-8
Palapa B4 May 13, 1992 Cape Canaveral, Pad LC-17B Delta-7925-8

Its well-known satellite is Palapa B2, which was launched from the Space Shuttle, but orbit insertion by NASA failed to reach geostationary orbit. The satellite was salvaged from LEO-orbit with a second Shuttle mission.

 

Series C

Two satellites of the HS-601 type were launched in 1996. As C1 had some battery problems, it became an insurance claim and Hughes bought back the satellite. With reduced availability it was then used by several other customers.

Palapa C2 May 16, 1996 Kourou ELA-2 Ariane-44L H10-3

 

 

 

 

Series D

The PALAPA-D satellite was manufactured by Thales Alenia Space – France, and launched on Chinese Long March 3B rocket on 31 August 2009. After performing in orbit test successfully, the satellite has been operating commercially in 113E orbital slot since 14 November 2009.

The PALAPA-D Satellite has more transponders than its predecessors (40 transponders compared to 36 transponders of PALAPA-C2). This “New Hot Bird”   has also more power and coverage. Having 45dBW EIRP @ peak, the C-band transponders cover the whole Indonesia, ASEAN countries, and spread out up to Australia and most of Middle East countries. Five Ku-band transponders cover Indonesia and neighborhood countries with equipped more power up to 53dBW.

Not only handling over its predecessor, PALAPA-D even provides more values to the various services included but not limited to broadcasting, Internet access, VSAT, and cellular backhaul services, in term of power as well as coverage. Direct to Home (DTH) and data communication services are another satellite service application being served through PALAPA-D for consumer and corporate applications. Along with those dedicated services, Indosat also provide satellite on demand service, such as news gathering, and or other special events. <http://www.answers.com/topic/palapa-1#cite_note-1>

All customers resided in PALAPA-D is now enjoying those advantages, as it part of Indosat commitment to serve customer even better.
