MEASAT Satellite Systems

from Wikipedia, the free encyclopedia

MEASAT Satellite Systems Sdn. Bhd. (formerly Binariang Satellite Systems) is a Malaysian communications satellite operator based in Cyberjaya .

The company offers pay TV and other communication services in Asia and operates a number of communication satellites that are launched under the name Measat.

history

In 1992 a decision was made in Malaysia to expand the domestic communication infrastructure, including the Binariang Sdn. Bhd. received a corresponding order. The project ran under the name Malaysia East Asia Satellite or MEASAT for short. In May 1994, Binaring signed a contract with Boeing to build the satellites, a ground station on Langkawi and the training of the Malaysian control team. In January 1995 Boeing was given the option for a second satellite. The efforts showed results in 1996 when the communications satellites MEASAT-1 and MEASAT-2 were launched from Europe's Center Spatial Guyanais in Kourou . They provided regional C-band and Ku-band coverage in parts of Southeast Asia and formed the basis for the development of local satellite TV providers. Binariang's satellite subsidiary became independent in 1998 and later became MEASAT Global Bhd Holding and MEASAT Satellite Systems Sdn. Bhd. renamed, which now operates worldwide. The MEASAT fleet currently consists of the satellites MEASAT-3a, MEASAT-3, MEASAT-2 and AFRICASAT-1, which are used in more than 145 countries and thus for 80% of the world's population in the Asia-Pacific region , in the Middle East, in Africa, Europe and Australia is received. The start of Africasat-1a is planned for 2012.

Satellites

MEASAT-1

MEASAT-1 (since January 2008 Africasat-1 or Afrisat 1) is a spin-stabilized satellite based on Boeing's 376HP satellite bus. It was brought into geostationary orbit on January 13, 1996 by an Ariane-44L H10-3 together with PAS 3R to the position 91.5 ° East. It transmits with twelve C-band transponders with 12 watts TWTA and five Ku-band transponders with 112 watts of power with a bandwidth of 36 and 54 MHz (EIRP: 41.5 dBW or 59 dbW). Twelve years were planned as the service life. The launch mass of the satellite is 1450 kg (886 kg in orbit).

MEASAT-2

MEASAT-2 (since the beginning of 2010 Africasat-2 ) is a spin-stabilized satellite based on Boeing's 376HP satellite bus. It was brought into geostationary orbit to the position 148 ° East on November 13, 1996 by an Ariane-44L H10-3 together with Arabsat 2B and supplies the eastern and southern parts of Asia, Hawaii and eastern Australia. It transmits with six C-band transponders with 12 watt TWTA and eleven Ku-band transponders with 62 watts (eight pieces) and 95 watts (the remaining three) with a bandwidth of 72 and 48 MHz (EIRP: 41 dBW) or 59 dbW). The launch mass of the satellite was 1450 kg (886 kg in orbit).

MEASAT-3

MEASAT-3 is a three-axis stabilized satellite based on Boeing's 601HP satellite bus. It was brought into geostationary orbit to 91.5 ° East on December 11, 2006 by a Proton BreezeM rocket and supplies Asia, Australia, the Middle East, Eastern Europe and East Africa. It transmits with 24 C-band transponders with 65 watt TWTA and 24 Ku-band transponders with 120 watt power with a bandwidth of 36 MHz each (EIRP: 42 dBW or 59 dbW). The satellite has four 4 XIPS-13 Xenon - ion engines . The launch mass of the satellite was 4765 kg (3220 kg in orbit). The planned service life is 15 years. The power take gallium arsenide -Solarzellenflächen with a wingspan of 26.2 m which also provide yet 9.8 kW electrical power available at the end of life of the satellite.

MEASAT-3A

MEASAT-3A is a three-axis stabilized satellite based on the Orbital STAR-2 satellite bus from Orbital Sciences Corporation . On June 21, 2009, a Zenit-3 SLB put it into geostationary orbit, also to the position 91.5 ° East. The satellite separated from the rocket six minutes and 24 seconds after launch. It supplies Asia, Australia, the Middle East and East Africa. It transmits with twelve C-band transponders with 60 watt TWTA and with twelve Ku-band transponders with 120 watts of power with a bandwidth of 36 MHz each (EIRP: 42 dBW or 55–59 dbW). The transmission takes place via two antennas with a diameter of 2.3 meters each (for C and Ku band) and an antenna with a diameter of 1.2 meters (C band) attached to the satellite body. The energy supply is provided by two gallium arsenide solar cell surfaces, which provide up to 3.6 kW of power for the payload. The launch mass of the satellite was 2417 kg. The planned service life is 15 years.

MEASAT-3B

The MEASAT-3B satellite was built by EADS Astrium on the basis of the Eurostar E3000 satellite bus . It has a takeoff mass of 5800 kg, an electrical output of 16 kW and is also at position 91.5 ° East. Its Ku-band capacity is 20 to 30 times higher than that of its predecessor. It has 4 antennas with an EIRP of 55–61  dBW that are aimed at the regions of Malaysia , Indonesia , India and Australia . The launch was from Center Spatial Guyanais on September 11, 2014 , and the satellite was handed over to Measat on October 16.

MEASAT-3C

MEASAT-3C would have been the name for rented Ku and S-band transponders on board the Australian satellite Jabiru-1 . The start was planned for 2015, but after the bankruptcy of the operator NewSat , the project was canceled.
