NigComSat-1R
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
