MEASAT (Malaysia East Asia Satellite) is the name of a line of Malaysian communications satellites owned and operated by MEASAT Satellite Systems Sdn. Bhd. (MYX: 3875, formerly Binariang Satellite Systems Sdn. Bhd.). As of 2006, the MEASAT satellite network consists of three geostationary satellites designed and built by Boeing Satellite Development Center (formerly Boeing Satellite Systems). MEASAT-1 and MEASAT-2 were launched in 1996 and MEASAT-3 in 2006.

The MEASAT-1 and 2 satellites were designed to provide 12 years of both direct-to-user television service in Malaysia and general communications services in the region from Malaysia to the Philippines and from Beijing to Indonesia. With the launch of MEASAT-3, the coverage extends even further to an area encompassing 70% of the worlds population.

In May 1994, Binariang Sdn. Bhd. of Kuala Lumpur and Boeing Satellite Systems signed a contract calling for the construction of the Malaysia East Asia Satellite (MEASAT) system. The system called for one Boeing 376 model spacecraft, equipment for a satellite control station on Langkawi Island, and training of Malaysian spacecraft controllers. Binariang exercised its option for a second satellite in January 1995.

MEASAT 1 has five high-power transponders in Ku band for the direct-to-user service, powered by 112-watt traveling-wave tube amplifiers. The regional service is provided on 12 transponders in C band, using 12-watt solid state amplifiers. MEASAT-2 has 11 active transponders in Ku band. Eight of these use 95-watt traveling-wave amplifiers, and three have 62 watts. There also are six active transponders in C band, powered by 12-watt solid-state amplifiers.

As Boeing 376 spacecraft, the MEASAT satellites have three enhancements over the standard model. They were the first in the Boeing 376 series to be fitted with gallium arsenide solar cells, which deliver 40 percent more payload power as compared to their silicon predecessors. They were also the first Boeing 376s to use Boeing Satellite Systems' lightweight, high-gain shaped antenna. The satellites also used a more efficient bipropellant system for stationkeeping and attitude control maneuvers.

Both MEASAT-1 & 2 satellites were launched on Ariane rockets from Centre Spatial Guyanais at Kourou in French Guiana. MEASAT-1 was launched in January 1996, and MEASAT-2 was launched in November 1996. MEASAT-1 is located in a geostationary orbit at 91.5 degrees East, and MEASAT-2 is located in a geostationary orbit at 148 degrees East.

In March 2003, MEASAT Satellite Systems Sdn. Bhd. of Malaysia ordered a Boeing 601HP satellite, designated MEASAT-3. MEASAT-3 will join the existing Boeing-built MEASAT-1 and MEASAT-2 spacecraft in the Malaysia-East Asia Satellite (MEASAT) system.

International Launch Services was contracted as the launch provider. Boeing will also provide an upgrade to the MEASAT ground facilities in Malaysia, as well as training and launch support services.

MEASAT-3 was launched successfully on the 12th of December 2006, 7.35 am (Malaysian Time, GMT +8.00 HRS) from the Baikonur Cosmodrome, Kazakhstan [1]. The Launch Event in Kuala Lumpur, Malaysia, was held with the MEASAT-3 launch broadcasted live via satellite transmission.

The MEASAT-3 was launched on board an ILS service vehicle Proton M/Breeze M with a five-burn to orbit sequence. It entered commercial service on Jan 25th 2007 at a geostationary orbit of 91.5 degrees East (co-located with MEASAT-1). The C band and Ku band now covers geographically remote areas such as Sabah, Sarawak, and North India and expands the MEASAT fleet's coverage to more than 100 countries embracing Australia, Middle East, Eastern Europe and Africa.

MEASAT-3 transponders' specifications:

EIRP (dBW) 41 (Global beam), 45 (Asia beam)
G/T (dB/K) +0.5 (Global beam), +2.8 (Asia beam)
TWTA power 65 Watts

Living the Dream.. (POEM)

Man of leisure,

I envy you.

Eternal sloth,

Comfort is your uniform.

Nothing leads to nothing,

You always reach your destination.

Man of leisure,

I envy you.

Jack of hobbies,

None you need to master.

Time spent fruitlessly,

Accomplishing all you set out too.

Man of leisure,

I envy you.

Morning till night,

Nothing is needed.

A man of excess,

All of life is an option.

1) Patience and perseverance have a magical affect before which difficulties disappear and
obstacles vanish. -John Quincy Adams-

2) People spend a lifetime searching for happiness; looking for peace. They chase idle dreams, addictions, religions, even other people, hoping to fill the emptiness that plagues them. The irony is the only place they ever needed to search was within. -Romana L. Anderson-

3) Motivation is what gets you started. Habit is what keeps you going. -Anonymous-

These Walls Don’t Lie Stranger Friend

What is this wall we need for
Even in the spring and winter?
I am keepin’ in and keepin’ out
the voices I hear;
on the other side.
Leaves rustlin’ from our two yards, of two trees,
Near, on the other side.
Gaps between us my friend stranger.
What do you mean when I know what I mean.
You haven’t seen, my natural unique or my yard of physique
I say we can be friends, don’t matta’ if we separated by this wall.
Be my friend, and I will be yours.
Just know there wil be a secret
…:::Between Us:::…
That is, you will never know
Stranger Friend what’s in my yard
and surely, in your yard.
Only two trees,
How’d I guess?
Leaves that had fallen [from Fall and Winter]

MaDaH dArI hUkaMa'.. renungilah..

  • Banyak diam tidak semestinya bodoh, banyak cakap tidak semestinya cerdik. Kerana kecerdikan itu buah fikiran. Orang cerdik yang pendiam lebih baik dari orang bodoh yang banyak cakap.
  • Menasihati orang yang bersalah, tidak salah, yang salah memikirkan kesalahan orang.
  • Kala orang menghina kita, bukan kita terhina. Yang sebenarnya orang itu menghina dirinya sendiri.

Apabila ditanya mengenai rahsia personaliti yang baik, seorang pemimpin pernah berkata:

“Saya tidak ada apa-apa yang rahsia. Sebenarnya anda masih belum belajar mengenai kehidupan. Tidakkah anda perasan yang anda boleh memberi warna kepada kehidupan, atau anda memang boleh menentukan reaksi yang anda mahu daripada orang yang anda temui.”

Pemimpin tersebut menambah lagi.

“Sememangnya amat mudah. Jika anda mahu mereka senyum pada anda, senyumlah dahulu. Jika anda mahu mereka mempunyai minat terhadap anda, tunjukkanlah yang anda juga berminat dengan mereka. Jika anda mahu mereka memuji anda, pujilah mereka dahulu. Orang akan melayan anda seperti anda melayan mereka. Sememangnya tidak ada rahsia. Lihatlah diri anda. Anda akan dapat buktikannya apabila anda berjumpa dengan orang yang baru anda temui.”

Lord Chesterfield berkata:

“Perasaan suka seorang yang lain adalah seperti magnet yang terkuat untuk menarik perasaan yang sama dari orang tersebut.”

Goethe, berkata:

“Jika anda mahu orang suka dan gembira bertemu anda, anda juga mesti mempunyai perasaan yang sama. Tunjukkan perasaan itu.”

Why I am here now and what I want.
I have been asked for a simple project to build the blog by myself and will be check by Puan NoorMaizatul Akmar bt Ishak. For that reason, I am preparing to finish my project that I have done through the Internet for build up my blog that help me to pass one of the project with a good grade that support my pointer.

I thought that the above two paragraphs is complete for my introduction. Then i hope you all can view my blog deeply and sincerely..


aku ingin kamu...

kau hadir saat aku memerlukan... penawar duka lara.... setelah lama gugur kesepian.. terbalutlah lukaku dengan harum cinta mu.. TERIMA KASIH ku ucapkan...
