MD, NigComSat , Mr. Timasaniyu Ahmed-Rufai
By Kunle Akogun
The December 19 scheduled launch of NigComSat-1R in China may be jeopardised unless the Nigerian Communications Satellite Limited could cough out N1.8 billion between now and close of work tomorrow.
Managing Director, Nigerian Communications Satellite Limited (NigComSat), Mr. Timasaniyu Ahmed-Rufai, who disclosed this in Abuja yesterday, said the money was the outstanding bill on insurance.
Ahmed-Rufai, who disclosed this during an interactive session with the Senator Gilbert Nnaji-led Committee on Communication, said the launch of the replacement satellite could only be permitted if the country paid the outstanding N1.8 billion before tomorrow.
He noted that if the country failed to launch the satellite as scheduled, the country might not get another launch window until after about one year.
The Nigcomsat boss said the danger of default in launching the satellite was that the satellite might disintegrate since it was not build to be left without launch for a long period.
Disintegration of the satellite, he said, might lead the country to lose about N41 billion (about $256 million).
NigComSat-1R was a replacement satellite for NigComSat-1 that had to be de-orbited on November 10, 2008.
"It was scheduled to be launched on December 19 in China but "the insurance of N1.8billion has to be paid by Friday failure which the country may not get another launch window," he said.
The managing director also used the opportunity to explain the difference in function between the National Space Research and Development Agency (NASRDA) and NIGCOMSAT to the committee.
He said NASRDA was to build and launch satellite, while NIGCOMSAT was to commercialise and deploy ICT services.
He noted that the launch of the satellite would create jobs opportunities and make broadband available as presently Nigeria is spending $500 million on internet services.
He told the committee that capacity building has been ongoing as indigenous engineers have been trained internationally.
Ahmed Rufai said Nigeria was the only country in Africa which fully owns a communication satellite.[/size]

Nigeria plans to relaunch satelite in December: officialЦитироватьLAGOS, Nov. 22 (Xinhua) -- The Nigerian Communications Satellite-1Replacement (NigComSat-1R) would be launched on Dec. 19, according to a top official with the Nigerian Communications Satellite.
The company's Managing Director Timasaniyu Ahmed-Rufai made this known in Lagos on Monday at the Stakeholders' Conference and Exhibition on NigComSat-1R, titled "Pre-launch Marketing and Sensitization on NigComSat-1R".
He said the new satellite would be sent into the orbit from China.
The managing director told his audience that 18 months after the launch of NigComSat-1 on May 13, 2007, the satellite was de- orbited on Nov. 10, 2008.
"We spent five months to analyze what happened to NigComSat-1 before commencing on the manufacturing of NigComSat-1R," he said.
He said the new device was a super hybrid geostationary satellite for communications and would also serve in telemedicine, e-learning and aircraft.
"The launch of NigComSat-1R is symbolic on different levels. For us at NigComSat Ltd., it is the end result of many years of hard work and sacrifice," he added.
"It is another step toward the fulfilment of our vision to be the leading satellite operator in Africa," he said.
"For the Federal Government of Nigeria, it is a prerequisite for a knowledge based economy, and to the ICT industry, NigComSat- 1R will serve as a critical infrastructure," the official told his audience.
Ahmed-Rufia called for the cooperation of the government and the ICT industry to enable the average Nigerian to reap the benefits of the launch.
According to him, while the de-orbiting of NigComSat-1 was disappointing, it paved the way for growth and improvement.
He called on the broadcast industry to take advantage of the opportunity to meet what he called the challenges of global migration in the industry.
NigComSat-1R has a life span of 15 years. Earlier, Minister of Communications Technology Omobola Johnson said the new satellite would add value and improve the fast growing ICT landscape in Nigeria, especially in the area of broadband Internet connectivity. "Recently, the International Telecommunication Union (ITU) rose up from its yearly meeting in Geneva, Switzerland, with a marching order to its member countries to make broadband connectivity available in at least 40 percent of households by 2012," she added.
"Nigeria is as a member of ITU will abide by ITU decision by creating an enabling environment for broadband Internet connectivity through adequate investment by both the government and the private sector," Johnson said.
She added that NigComSat-1R would domesticate broadband services by curtailing capital flight of about 500 million U.S. dollars yearly.

Mon, 28/11/2011 - 3:10am | CHIMA AKWAJA
China is set return Nigeria into space with the re-launch of a replacement satellite for Nigeria communication satellite on December 20, 2011 after three years absence due to a heat flare which destroyed Nigeria's first communication satellite.
NigComSat-1R will be a major boost to the ICT industry especially the telecommunications and broadcasting sectors as it would help in easily migrating from analogue to digital broadcasting using the Direct-To-Home (DTH) service that is entrenched in NigComSat 1R.
The new satellite called Nigeria Communications Satellite Replacement (Nigcomsat 1R) is a super hybrid geostationary satellite with C, Ku, Ka and L bands and 44 transponder payloads. NigComSat-1R will provide optimal and cost effective voice, data, video, internet and application services solutions.
Its Ka-band employs spot beams that are distributed for trunking and broadcast purposes respectively; Ku-band payload with 14 operational channels; C-band payload with 4 transponders and L-band payload with 2 transponders. Its features and benefits unveiled to the information and communications technology sector in Lagos is expected to help Nigeria migrate from analogue to digital broadcasting seamlessly.
Engineer Timasaniyu Ahmed-Rufai, managing director, NigComSat Limited, stated that the launch of NigComSat-1R would ensure that Nigerians have access to quality communication without necessarily paying exorbitant fees for the opportunity and redress the long term damage to the Nigerian broadcasting environment created by years of technological dumping and inconsistent approach to signal and content distribution by practitioners.
Vice President, China Great Wall Industry, Mr. He Xing, said the goal of NigComSat-1R was to provide coverage over Africa, the Middle East, Europe and parts of Asia, thus improving communication access which would force down the cost of telecommunications in the country especially in the area of internet and GSM communication.
The Minister of Communications Technology, Mrs.
Omobola Johnson, who was represented by Mr. Ola Ogunneye, special assistant on ICT said that the federal government's plan to launch Nigeria Communications Replacement Satellite (Nigcomsat 1R) into orbit would bring down the cost of bandwidth used for communications services.
The Director- General, National Broadcasting Commission (NBC), Engineer Yomi Bolarinwa, said the hybrid Nigcomsat 1R would help broadcasting and cable television companies bring digital broadcasting to millions of Nigerians.
Speaking on future trends in broadcasting technology, he said a lot of convergence was going on, noting that in the past three years, multi-platform delivery, transition to high definition television (HDTV), files based/tapeless workflows, and internet protocol network content delivery have become the order of the day.[/size]

ЦитироватьNigeria and the Quest for Communications Satellite[/size]
01 Dec 2011
With the planned launch of Nigeria's communications replacement satellite called NigComSat-1R from China on December 19, 2011, by the Nigerian Communications Satellite Limited (NigComSat), Emma Okonji examines why the first satellite that was launched in 2007 failed in orbit, the renewed efforts for a successful launch of another satellite and its economic benefits.
Passion for Communications Satellite
Established by government in 2006, the Nigerian Communications Satellite Limited (NigComSat) has a strong passion to build and launch communications satellites through which it will serve both government and the public in delivering communications services and applications through the lease of transponders to businesses in Nigeria and beyond.
In 2007, one year after it was established, NigComSat, led by its Chief Executive Officer, Timasaniyu Ahmed-Rufai, took the first bold step to launch a communications satellite for Nigeria, called NigComSat-1.
Nigerians were glad at heart when they saw the efforts of Ahmed-Rufai and his technical team culminated into success when the satellite was eventually launched into space in 2007 from China, by the China Great Wall Industry Corporation (CGWIC), builders of NigComSat-1.
NigComSat staff and Nigerians who knew the benefits of communications satellite were walking shoulder-high shortly after its successful launch, expecting that few months later, Nigerians would be able to use the satellite in monitoring communications and broadcasting activities as well as security surveillance.
Unknown to everyone, there was a looming danger surrounding the satellite in orbit, which eventually struck few months after its successful launch, a situation that led to the collapse of the vital functions of the satellite and it was de-orbited on November 10, 2008. In technical parlance, de-orbiting is a process of shifting the satellite from its original position in space to a distant position, from where it will eventually go into extinction.
The essence of de-orbiting is to maintain the satellite space for a replacement and to avoid situations where the malfunctioning satellite will be sending wrong signals to the ground control stations.
Why the Initial Satellite Failed
Addressing stakeholders' conference in Lagos on the planned replacement satellite, Ahmed-Rufai explained why the initial satellite failed and the need to launch several other satellites into space.
According to him, the satellite was successfully launched in 2007, but few months after its launch, there was a spark in space, and the route of the spark was close to Nigeria's satellite. The spark was so severe that it instantly cut off one of the strings carrying vital communications information flow, a situation that rendered the entire satellite useless since it could no longer function as a result of the cut that was caused by the high degree spark.
With the colossal damage, we had to de-orbit the satellite and prepare for another satellite launch.
The failure rate of satellites in space according to Ahmed-Rufai, is beyond human control and could be devastating, and that is why most countries have several satellites in space, having experienced satellite failure in the past.
China has over 12 communications satellites in space and they are still building because that is the direction of the future growth in global digital revolution. Nigeria is not the only country that has suffered satellite loss, and some countries had same experience after the Nigeria's bitter experience.
Assurances of the Success of NigComSat-1R
At the recently concluded 3-day stakeholders' conference on NigComSat-1R in Lagos, Ahmed-Rufai spoke extensively on the planned launch of a replacement satellite and its' state of readiness for launch.
According to him, the replacement satellite known as NigComSat -1R "has been fully integrated and every necessary performance test has been carried out on the satellite. It had already been moved to its launch site in central China, from where it would be launched on December 19, 2011.
The replacement satellite, according to Rufai, is a Hybrid Satellite, since it will function beyond communications, providing navigational services for the aviation and maritime industries as well.
Vice President of CGWIC, Mr. He Xing, who flew from China to attend the stakeholders' conference and exhibition on NigComSat-1R, also confirmed the readiness of NigComSat-1R for the December 19 launch. Xing said the replacement satellite would be launched on the DH-4 platform of CGWIC.
He explained that the ground control of the satellite would be carried out in Nigeria by Nigerian engineers that have undergone intensive training in China in recent times.
"We have provided training for over 60 engineers sent by the management of NigComSat, and they are capable of controlling the satellite from the ground station in Nigeria, and providing services to Nigerians and Africans. With over 50 years in the practice of space technology, and with the successful launch of several satellites from China by CGWIC, we are optimistic that we are going to have a successful launch of NigComSat-1R this month," Xing said.
China, he said, would continue to give support to Nigeria in developing its space technology and CGWIC would always provide back-end support to NigComSat, to enable it provide world-class satellite services to Nigerians as well as to people in other African countries.
Economic Benefits
Minister of Communications Technology, Mrs. Omobola Johnson, in her key note address at the stakeholders' conference on NigComSat-1R, said "the satellite will no doubt add value and improve the fast growing ICT landscape in Nigeria especially in the areas of broadband internet connectivity.
Nigeria is a hurry to achieve the Millennium Development Goals (MDGs), and only recently, the International Telecommunications Union (ITU) rose up from its yearly meeting in Geneva, Switzerland with a marching order to its member countries to make broadband connectivity available in at least 40 percent of home holds by 2012.
Nigeria is a member of ITU, and will abide by the ITU decision by creating the enabling environment for broadband internet connectivity through adequate investment by the government and private sector. The planned launch of NigComSat-1R will address the issue of broadband availability and help Nigeria achieve its MDGs."
Ahmed-Rufai said that satellite television customers in the country and other parts of Africa, are currently getting programming contents through Direct To Home (DTH) providers, but explained that the communications satellite, when launched, would, support players in the Nigerian broadcast industry to aggregate hundreds of channels and deliver same directly to homes across the country.
The role of NigComSat-1R, according to Rufai, is to foster the growth of broadcasting industry as it will allow broadcasting concentrate on the provision of quality content in order to realise maximum revenue.
He said the satellite would also act as open doors to attract foreign direct investments into the country.
Technical Manager of NigComSat, Inuwa Danladi Alhaji who presented a paper on Homeland Security Challenges, gave several reasons why Nigerians and the Nigerian government should embrace communication satellite for national development.
According to him, NigComSat-1R would provide good security for Nigerians and Africans; enable better flow of information from satellite to multi-channels; improve interconnectivity among the military (Army, Navy and Air force); enhance communication across the Police force; provide easy access to information seekers; and check disaster management and control, among others.
"Considering that delivering basic healthcare and education to remote and sparsely populated regions was almost an insoluble challenge, the launch of NigComSat-1R will provide the much needed bandwidth to take these services across the country. The satellite will facilitate NigComSat secondary school NET project, which is intended to connect selected 10 secondary schools in each state of the federation to a central point.
It will also enhance virtual campuses in remote locations, which shall be connected to other locations," Inuwa said.
The Role of NigComSat-1R
NigComSat-1R, according to Ahmed-Rufai, is a bend pipe satellite that has a wide area of coverage, provides higher bandwidth, has a long life span of 15 years and is best for broadcasting and multicasting.
The launch of NigComSat-1R will ensure that Nigerians have access to quality communication without necessarily paying exorbitant fees for the opportunity and redress the long term damage to the Nigerian broadcasting environment created by years of technological dumping and inconsistent approach to signal and content distribution by practitioners.
NigComSat-1R will be able to achieve this feat through Payloads like Ka-band, which employs spot beams that are distributed for trunking and broadcast purposes respectively; Ku-band with14 operational Channels; C-band with 4 transponders; and the L-band with 2 transponders.
NigComSat-1R intends to foster the growth of the broadcasting industry and will serve as an Internet back- bone that will enable Internet Service Providers (ISPs) to buy data on a complete bundle to be transmitted through NigComSat-1R.
The successful launch of the Satellite will allow broadcasters concentrate on the provision of quality content in order to realise maximum revenue. Also, the expected low rates of bandwidths from NigComSat-1R will attract broadcasting and telecommunications organisations, both local and foreign.
Future Trends in Broadcast Technology
In a paper presentation on the future trends in broadcast technology, using communications satellite, Director General of the National Broadcasting Commission (NBC), Yomi Bolarinwa said nobody can accurately predict the future, especially in broadcasting where technological developments is a major driving force.
According to him, the possibilities for creating new services have been enabled by three technologies namely Digitalisation, Computerisation and Packet-based Switching and the three technologies have also created conducive atmosphere for synergy between the hitherto divergent communication platforms.
These technologies are the driving force behind the Internet Protocol (IP) revolution; the convergence process and emergence of Next Generation Network (NGN) technologies, which in turn have reshaped and restructured different communication sectors and markets.
On Digitalisation, Bolarunwa said the development from analogue to digital is by far the most fundamental precondition for any other technological changes we have witnessed in recent years.
Digitalisation enables the integration of different services in the same network and enables synergy to be reaped in the whole value chain of service- production, distribution and consumption.
On Computerisation, he said "the digital code is enjoying a renaissance of late because of the process of receiving, storage and retrieval capacity of computers".
The role of computers in production and consumption parts is quite obvious.
For the Packet-based Switching, he maintained that Packet switched technologies have had an important role in the more efficient utilisation of the available resources in different network infrastructures and the creation of platforms enabling multi-service delivery in the same network, enabling real convergence.
Speaking on convergence of technologies, Bolarinwa said the term convergence eludes precise definition, but it is most commonly expressed as "the ability of different network platforms to carry essentially similar kinds of services, or the coming together of consumer devices such as the telephone, television and personal computer."
According to him, perhaps the most important impact of digitalisation on broadcasting was the phenomenon of convergence and it remained part of a broader trend of technology change that is blurring the distinction between all sectors in communications industry: the telecommunications, the Internet, and broadcast services.
NigComSat-1R, he said would provide the much needed platform for technology convergence, which he said, remained the future trend in global digital revolution. Nigeria, he added, needs communications satellite to harmonise its growing technologies, aimed at meeting its Millennium Development Goals and boosting economic development.[/size]

Powerful Nigerian satellite ready for liftoff from ChinaЦитироватьChina will launch a massive Nigerian communications satellite Monday to link Africans with television programming, education services and navigation signals.
Manufactured by the China Academy of Space Technology, the Nigcomsat 1R satellite will replace a craft that lost power and failed in November 2008, less than 18 months after its launch on a Chinese rocket.
Nigcomsat Ltd., a company chartered by the Nigerian government, will operate the satellite for up to 15 years.
Nigcomsat 1R "will provide optimal and cost effective voice, data, video, Internet and application services solutions," the satellite's operator said.
Liftoff is expected shortly after 1630 GMT (11:30 a.m. EST) Monday, or just after midnight Beijing time on Tuesday.
An 18-story Long March 3B rocket will streak into space from the Xichang launch base in Sichuan province in southwestern China.
The three-stage rocket, boosted off the launch pad by four strap-on engines, will reach orbit 10 minutes into the mission. The rocket's hydrogen-fueled third stage will ignite a second time to place Nigcomsat 1R in an an oval-shaped transfer orbit with a low point of 124 miles, a high point of 26,092 miles and an inclination of 24.8 degrees, according to China Great Wall Industry Corp., the state-owned commercial sales firm for the Long March rocket family.
Separation of the 11,243-pound satellite is scheduled less than 26 minutes after liftoff. Nigcomsat 1R will ultimately be positioned in geosynchronous orbit over the equator at 42.5 degrees east longitude.
Nigcomsat 1R is based on China's DFH-4 spacecraft platform. China has reached agreements to build DFH-4 communications satellites for several non-traditional players in the space industry, including Pakistan, Nigeria, Venezuela, Laos and Bolivia.
Nigeria ordered the replacement satellite from China in 2009 at "no extra cost to the Nigerian customer" after the failure of the first Nigcomsat spacecraft, according to China Great Wall Industry Corp.
Nigcomsat 1R's communications package includes 28 active transponders and seven antennas reaching across sub-Saharan Africa, Europe and Central Asia.
The transponders will broadcast in C-band, Ku-band, Ka-band and L-band, according to Nigcomsat.
China added several upgrades to Nigcomsat 1R to improve its performance over the preceding Nigcomsat 1 satellite. A Ku-band spot beam on Nigcomsat 1R will provide communications links between Nigeria and China, according to Nigcomsat's website.
Nigcomsat 1R could stimulate economic growth in Africa, helping create jobs and saving customers expensive charges for telephone calls and broadband Internet access.
The satellite's C-band payload will reach across Africa, while its Ku-band transponders will be aimed at regions of southwestern Africa and China. The Ka-band system will be wired into spot beams focused on Europe, Nigeria and South Africa, according to Nigcomsat.
Nigcomsat 1R will transmit two L-band navigation channels make for more accurate satellite positioning services in Africa.

КА отделился, орбита в номе - можно идти праздновать Пусть управленцы по КА работают. Но на Протоне даже на промежуточную так быстро не выходит :D

ЦитироватьABUJA, March 19 (Xinhua) -- China Great Wall Industry Corporation (CGWIC) handed the recently launched NigComSat 1-R to its Nigeria counterpart on Monday at the Obasanjo Space Center in Abuja.
NigComSat 1-R, which was launched on Dec. 20, 2011 and successfully positioned in its geostationary orbit a week later, has completed the in-orbit test and is ready to hand over to Nigeria Communications Satellite Limited (NIGCOMSAT) for commercial operation, said Yin Liming, the CGWIC president.
CGWIC is fully prepared for the immediate takeoff of the following-on satellite program, namely Nigcomsat 2 and Nigcomsat3, with all technical and contractual details discussed and agreed, he said.
"I am indeed very delighted to receive the symbol of our proudly renounced satellite – NigComSat 1 replacement today from the China Great Wall Industry Corporation. This event marks the beginning of full commercialization of the satellite for the benefit of Nigeria and indeed the Africa continent and the global community," said Turner T. Isoun, the NIGCOMSAT board chairman.
Nigeria's communications satellite NigComSat 1 was successfully launched in 2007 in China but de-orbited in November 2008 due to malfunction of the solar array deployment assembly. China decided in 2009 to build NigComSat 1-R to replace the defunct one without adding additional costs to Nigeria.
NigComSat-1R, covering Central, Western and Southern Africa, Central and Eastern part of Europe, and some areas of Mid-Asia, will be mainly used for communications, broadcasting, tele- education, broad-band multimedia service and navigation service.
