Nigeria is the second largest after in India in Neo-natal deaths .The first   24 hours after birth determine the most critical period for the survival of Neo nate. Of the one million neo natal deaths every day one third are in India .large number of preterm births is the reason for around 50% of neonatal mortality

Satellite internet is traditionally provided by geo-stationary satellites which orbit at 35000kms above the earth surface with a delay of 600 millisecond which is very high. While o3b’s satellite orbit at relatively low latitude of about 85kms with 150 millisecond delay.

These satellites can even work when they are in motion relative to earth surface which is possible by beam-forming technology.
