Paksat 1R [SUPARCO]

Pakistan's SUPARCO signed in October 2008 a contract with China Great Wall Industry Corporation (CGWIC) for the on orbit delivery of the Paksat 1R communication satellite. The DFH-4 based satellite will have a service life of 15 years and will be launched in 2011 on a CZ-3B/E booster.

By the end of 2011, Pakistan plans to replace Paksat 1 with the new communication satellite Paksat-1R which will be manufactured exclusively for Pakistan. The satellite will support all conventional and modern Fixed Satellite Service (FSS) applications. The satellite will have a total of up to 30 transponders: 18 in Ku-band and 12 in C-band. To ensure high degree of reliability / availability of the system, two fully redundant Satellite Ground Control Stations (SGCS) would be established in Karachi and Lahore, one to act as the main and the other as backup respectively.

Nation:    Pakistan
Type / Application:    Communication

SUPARCO to launch Paksat 1R satellite[/size]

Submitted by Aatif I.Butt on августа 5, 2011 - 04:41 M



Pakistan will launch a telecommunication satellite "PAKSAT 1R" on the date of August 14, 2011. This satellite will replace the current satellite communications system developed by Hughes.

This was stated by Secretary SUPARCO, Arshad H Siraj on Monday. He said the satellite will replace the current PAKSAT 1, which is inactive and obsolete next year. Satellites have been showing signs of the eclipse 88 days a year. In PAKSAT 1R, the letter "R" means the replacement.

Telecommunication satellites are put in orbit 35,700 km above the equator, and on that particular altitude they move in-sync with Earth, thus completing the rotation in 24 hours and remaining stationary with respect to a particular position on the ground, which is why they are also called "geostationary satellites". However, only a limited number of satellites can be placed in that particular orbit because only one satellite can be put on each degree. Hence, 360 satellites can be placed in an imaginary circle above the globe.

The International Telecommunication Union (ITU) allocates the satellite place in geostationary orbit on a first-come-first-serve basis. But after allotment of a position, a deadline is needed for a party to launch its satellite in a given time and incase of failure, the allotment is handed over to other nations or parties who were in queue.

According to Secretary SUPARCO, in the 1980s, Pakistan booked eight slots in the orbit. In mid 90s Pakistan Telecommunication Authority (PTA) inked an agreement with Alcatel for a satellite. But in the mean time, a few telecommunication satellites launches failed worldwide and other problems halted the launch of the Pakistani satellite, causing Alcatel to cancel the agreement. Pakistan then also lost its allotted slots in orbit.

The deadline of the only slot left, 38° East, was April 19, 2003 and after that Pakistan also lost this space. The Former President of Pakistan, Pervez Musharraf asked the authorities to find a solution. A high level committee reported that buying and replacing a satellite of Hughes is the only option to secure the slot.

So Pakistan bought the Hughes satellite designed for Indonesia and moved it in the occupied slot in December 2002.

A hallmark of Pak-China joint venture, Paksat 1R will be launched on August 14, 2011, the Independence Day of Pakistan, which also happens to be the date for the 50th anniversary of SUPARCO. Working on this project will also give experience and confidence to Pakistani scientists and engineers. Many of the testing elements have been developed by experts of SUPARCO.[/size]

New communication satellite 'PakSat-1R' important for many reasons: Khan[/size]    

BEIJING, AUG 8 (APP): Pakistan's Ambassador to China, Masood Khan  has said that Pakistan's new communication satellite—PakSat-1R, is important for the country for many reasons. "It is a symbol of Pakistan-China cooperation in the area of space science and technology. It is the first of the kind to be launched by China and Pakistan. Therefore it establishes a new platform, and it marks a new beginning" said Ambassador Khan in an interview with China News Agency on the occasion of launch of PakSat-1R from China. The use of satellite would bring direct benefits to Pakistan's  economy, Khan said adding that it would refine and enhance country's capabilities for the use of broadband Internet, digital broadcasting,  mobile telephony, and disaster prevention and management. All these capabilities will enable Pakistan to focus more sharply on social development, especially on education and health sectors, he said.

The Pakistan Communication Satellite—PakSat-1R, is due to be launched in space from Chinese satellite launching site located at Xichang city during the second week of current month, depending on weather conditions. It will replace Paksat-1.
Ambassador Khan said "As we accomplished this goal of launching PakSat-1R, we will swiftly move on to expand our collaboration with China in related fields of space science and technology".
The launching of the satellite, he said coincides with the celebrations of 60th anniversary of diplomatic relations between Pakistan and China.
Masood Khan said Pakistan and China are moving into the higher stages of aerospace cooperation. Remote sensing satellite is one such area. This satellite will cover crop monitoring, weather forecasting, urban planning, disaster preparedness and response, earth observation, and oceanography. These applications will have a direct impact on agriculture, industry and services sectors of Pakistan, vital for economy.
Ambassador Khan said last year Pakistan was hit by massive floods which caused large scale devastation across the country. It was at that time that the country fully realized the importance of a remote sensing satellite.
In the long term, he said we also want to cooperate with China on satellite designs to develop Pakistan's indigenous capability.
He expressed Pakistan's desire to participate in China's Manned Space as well Deep Space Exploration programmes.
He, however regarded it as something for the future. "It is our desire that the first non-Chinese astronaut to travel on board a Chinese spaceflight is a Pakistani".
Referring to the advancement made by China in space technology, Ambassador Khan said that China is constantly forging ahead at a brisk pace. It has made extraordinary strides into space science and technology as well as aerospace industry.
Ambassador Khan said China's space technology industrial base is expanding.Shenzhou 7, the third manned spaceflight has established a new threshold for China.
He, however said that China is not sitting on its laurels. It  is constantly moving forward. It has already planned Shenzhou 8 which  will be docked with Tiangong 1 space module. Tiangong-1 will place the  first portion of China's planned space laboratory in orbit. This will  be a breakthrough. The docking of Shenzhou 8 and Tiangong 1 is expected  to be followed by Shenzhou 9. The Beidou is yet another technological achievement as China can launch and operate complex systems in space.
These are all new frontiers that China is conquering, he remarked.
The people of Pakistan, Ambassador Khan said, are proud of these scientific achievements of China.[/size]

Launched on-time (there are a lot of Chinese bloggers "twitting" on the launch at this moment). The third stage and the S/C should be in LEO by now...

Lift off would have occurred before 1625UTC

even before 1617UTC...
