NigComSat-1R is a replacement satellite for NigComSat-1 Satellite. It is a critical ICT backbone infrastructure to drive the National ICT revolution in providing revenue diversification for the Nation and offering cost effective solution and affordable access to meet Nigeria’s telecommunications, broadcast, aviation, maritime, defense and security needs. NigComsat-1R has the same features as NigComSat-1, with modifications on the payload aimed at addressing domestic and International market needs. It is a super Hybrid, high power, quad band Geo-stationary satellite which will provide optimal and cost effective voice, data, video, internet and application services solutions.

FEATURES

Design features
- Bus: DFH-4 Platform
- Launch Mass: 5150 kg
- Launch Vehicle: LM-3B/E
- Launch date: December, 2011
- Orbital location: 42.5 E
- Service life: 15 years
- NigComSat-1R is built on a hybrid satellite with radiation-hardened technology, high reliability,
  onboard software re-programmable ability, fault tolerance, redundant components and high
  efficiency.
- Stronger footprints and centre beams over the African Continent
- Better look angles and shorter latency for intra Africa communication traffic
- More powerful signal strength.
- Increased reliability and availability of Ku-band due to adequate fade margin compensation for
  attenuation losses by rain - Reduced cost of deployment for VSAT installations through acquisition of
  smaller equipment
- Availability of Ka band for broadband services at lower cost arising from the frequency re-use
  techniques, competitively priced transmission capacity, small antennas and reduced terminal prices

Payload Configuration
The communication Payload comprises of 40 Transponders; 28 active and 12 redundant as shown below:
- C-band: 4 Active transponders
- Ku-band: 14 Active transponders
- Ka-band: 8 Active Transponders
- L-band: 2 Active Transponders
- A Seven (7) Service Antennas
Footprints and Coverage Areas
- Ku-band ECOWAS 1 BEAM EIRP 53Dbw/49dBW
- Ku-band ECOWAS2 BEAM 48dBW
- New Ku-band (oriental) with content
- C-band BEAM 43.44dBW/38dBW
- Ka-band beam
- L-band navigational Beam
- L-band: Global coverage; Provides Navigation Overlay Service (NOS) based on the European
  Geostationary Navigation Overlay Service (EGNOS); Two L-band signals transmitted, L1 & L5 ;
  Receivers in two for one redundancy; SSPAs in four-for-two redundancy

chineese engineers successfully RE-injected another saterlite into orbit yesterday,our presidet congratulates all nigerian on the development.pls nairalanders what are the benefits of this innovation to the masses?

I thought as much. After all this while no one could answer. @op there are a lot of benefit to Nig like u have stated above in your post all its uses and function. But i guess your question is what benefit is there to the common man? Well the painful answer is none. Forget what those rubbish IT expert paid by the govt try to explain. There is no single benefit to the ordinary Nigerian. The benefit will be reflected in the country's  annual GDPA.  More source of income to the country. So if we have good leaders perhaps the ordinary man will see the benefit but if  not, pls just remove your mind.
One physical effect is that when you receive a text message on your phone the number start with 234, with NIGCOMSAT1R the number 234 will be eliminated. That is if the network provider uses NIGCOMSAT1R. There are other  minor effects you will see when it kick start.
