Nigeria from December 19 will rewrite history when it returns to space with the launch of its communications satellite, tagged Nigcomsat 1R. The event is slated for Xichang, China. Time is 5pm local time.
Nigcomsat 1R is a replacement satellite of Nigcomsat 1 which was deorbited on November 10,2008 due to solar array problem.
It was built by China Great Wall Industries Corporation (CGWIC). The replacement satellite which is due for launch next week is at no cost to Nigeria.
Explaining the benefits of the satellite to a few ICT journalists recently, Managing Director, NIGCOMSAT ltd, Engr.Timasaniyu Ahmed Rufai said that the launch is expected to boost Nigeria’s Global Competitive Index ,GDI ranking even as the services it will provide for telecommunications, broadcast, broadband internet, among other customers will be greatly enhanced in Nigeria’s race to achieve the Vision 20:2020 goals.
NIGCOMSAT Limited was incorporated as a limited liability company in April 2006. NIGCOMSAT Limited is responsible for the operation and management of Nigerian Communications Satellites starting with NigComSat-1 which was launched in May 2007 and de-orbited after 18 months. A replacement satellite, NigComSat-1R which has the same features but with a few modifications as NigComSat-1.
NigComSat-1R, which is the second Nigerian Communication satellite, is to be placed into a geosynchronous orbit and positioned at 42.5oE.
It has a launch mass of 5,100 kg, and has an expected service life of 15 years. Meaning that by 2026 Nigeria will have to launch a new satellite in the same orbital slot.
According to Rufai, “the satellite will provide Ku-band, C-band, Ka-band and Navigation payloads capability. The Ku-band payload will have 14 operational channels, 2 fixed beams over Western and Eastern Africa. The C-band payload will have 4 channels with coverage of Western Africa.
The Ka-band payload will have 8 channels providing communications using 3 fixed spot beams over Europe, South Africa and Nigeria for trunking services and broadcasting”.
“The Navigation payload shall receive 2 uplink signals at C-band covering Nigeria and Europe, and transmit 2 downlink signals at L-band, L1 and L5, using a global coverage.
The spacecraft is designed such that each Radio Frequency (RF) channel shall meet the specified requirements, work well throughout its Service Life including eclipse conditions and also work well with allowance for degradation, wear-out and radiation damage”.
NIGCOMSAT said it has over 200 trained and equipped engineers and a well established ground control station at Abuja, Nigeria and a backup station at Kashi, China for the spacecraft tracking & control, Payloads Management and technology customisations & domestication.
Rufai added that “our strategic plan is centred on using our assets, the staff, the satellite and complementary ground infrastructures as an extraordinary vehicle to drive the National ICT revolution in pursuit of self-reliance and required skills for engineering and technology domestication of secured satellite bandwidth and telecommunication services for defence, security outfits and other strategic telecommunications and broadcast needs of the nation.
Additionally, NIGCOMSAT seeks to partner with all stakeholders to complement existing terrestrial telecommunication infrastructures to promote universal access through innovative, affordable, high speed broadband telecommunication services to enhance ICT usage, ICT skills and increase IDI (ICT development index) of Nigerian citizens.
This will ultimately diversify monolithic national revenue, create jobs, and improve security and socio-economic development of Nigeria” Stating sector by sector, how his company can benefit the Nigerian economy, Rufai said that for instance, in: Services and Applications The company as a commercial satellite operator has the mandate to offer wide range of Information and Communications services and applications within and outside Nigeria under its satellite’s footprints.

These includes but not limited to Satellite modems, Antennas, feeds, switches, biometric systems, e-voting systems, RFID based systems, silos etc.
A-Telecommunications Network Infrastructure deployment and alliance with other network operators.
The Uniqueness of Satellite Communication Satellite communications and indeed NIGCOMSAT in Nigeria provides unique competitive advantages over terrestrial networks of any organisation in the country such as: Ubiquitous availability Satellite communications is the only telephony and broadband wide-area network technology that is available everywhere. Meaning uniform services for all locations in Nigeria and indeed all areas where we have footprints. All that’s needed is a clear view of the sky.
Managing the communication network is also simpler and less expensive, since there is one point of contact for all locations, versus multiple local service providers and problematic demarcations between them.
Security & privacy Satellite networks are more secure and private than alternative terrestrial technologies, making them the technology of choice for governmental agencies, security organisations, military and enterprises that require high levels of security.
IP traffic across the internet crosses many computers, providing multiple points of access to private traffic. Satellite communications does not travel across third party terrestrial computers, minimizing chances of unapproved access.
Traffic can be encrypted using the most advanced algorithms to ensure that data will not be compromised. NIGCOMSAT can provide the military, the police and all other security agencies with the connectivity for their defence and internal security needs.
Terrestrial-free network Satellite networks are independent of terrestrial disruptions, making them an excellent solution for communication backups for terrestrial networks. They are also useful for disaster recovery and quick-deploy solutions, enabling communication services to be quickly restored.
Reliability Satellite networks have far fewer potential points of failure than terrestrial solutions, and built-in redundancy at almost every level, satellite networks provide unmatched reliability. Typical satellite networks can assure 99.95% availability to all sites, regardless of location.
Terrestrial networks have multiple potential points of failure. To add to the challenge, terrestrial network providers may not be able to fix outages without third-party carriers or work crews. Both telephony and modern broadband networks are challenged to provide this level of nationwide reliability.
Multi-cast content distribution Satellite’s inherent strengths as a broadcast medium makes VSAT networks ideal for the distribution of bandwidth-intensive information — data, video or audio — to large numbers of remote locations.
A terrestrial network requires sending separate and identical messages to all recipients, consuming valuable bandwidth and server resources. Satellite multicast technology eliminates duplicate transmissions and maximizes the efficiency of existing servers and networks, freeing valuable bandwidth. There’s no extra overhead at the hub or in the satellite. The only added cost for each recipient is the VSAT. That translates to significant cost savings.
Satellite communications provides advanced communications infrastructure to regions that do not have adequate terrestrial infrastructure as is the case in Nigeria through: Superior Economics Satellite networks are much less costly to deploy, maintain and operate in many cases than terrestrial network technologies. Terrestrial networks require heavy infrastructure, whether they are telephony networks (based on copper wiring, fibre optic cables, radio or microwave towers), or broadband data networks (such as Frame Relay, DSL, ISDN and cable).
In remote areas, building such networks is often prohibitively expensive. VSATs are not only significantly less expensive to deploy, VSATs built for low power consumption can run without electrical power infrastructure, using simple solar panels.
Rapid deployment & installation Satellite networks can be rolled out to hundreds or thousands of locations in a fraction of the time required for a comparable terrestrial network. VSAT installation requires only a single vendor, so multi-vendor coordination is not needed.
An installation can usually be completed in a matter of hours, no matter where the site is located, meaning complete network deployment can be accomplished in a matter of weeks, rather than months. Satellite network installation and deployment are indeed quick and simple.
Flexibility & Expandability VSAT technology has an unmatched ability to support a wide range of devices and applications. Single platform scan provide voice, fax, data and video communications. Data networks can support advanced functions including IP multicasting.
VSATs are software upgradeable, adding new capabilities usually do not require a technician at the remote locations. The modular design of VSAT systems also allows for maximum scalability and fast upgrades — with an ease and simplicity not possible with terrestrial networks.
