SintelSat, a global satellite solutions provider, and O3B Networks, Medium Earth Orbit (MEO) satellites operator are working together to provide solutions for fiber quality satellite-based, global internet backbone for telecommunications operators (telcos) and internet service providers (ISPs) in emerging markets. O3B Networks MEO satellites are scheduled for deployment on late 2010. The system will combine global reach and the speed of a fiber optic network with investment and operational support from Google Inc., Liberty Global, Inc. and HSBC Principal Investments.

SintelSat's fiber-quality satellite-based solutions will provide telcos and ISPs with a low-cost, high-speed alternative to connect their 3G, WiMAX and fixedline networks to the rest of the world. This will allow billions of consumers and businesses in more than 150 countries to benefit from high-speed internet connectivity for educational, medical and commercial applications.

MEO Constellation
MEO Satellite Design — Orbit at 8,063 Km — 288 minute orbital period — In-orbit redundancy — 10 years minimum life time — First 8 satellites to launch in Nov. 2010 via Sea Launch — 2nd, 3rd launches in 2011   MEO satellites operate 8,063 km. (5,010 miles) from Earth. This altitude is 4.8 times closer than GEO satellites, which orbit the Earth at a fixed distance of 35,786 km. (22,300 miles). The reduced distance eliminates the voice delay of typical satellite communications and enables real-time video conferencing, call-center development, and interactive web 2.0 applications in emerging markets.
