Outernet is a global network of cube satellites
(Cubesats) broadcasting Internet data to all over the
Outernet project is currently under development by a
US organization Media Development Investment Fund
Outernet’s goal is to provide free access to internet
data through Wi-Fi, made available effectively to the all
part of the world.
It is a modern version of shortwave radio, or BitTorrent
There are more computing devices in the world than
people, yet less than 40% of the global population has
access to the wealth of knowledge found on the internet.
In some places, such as rural areas and remote
regions, cell towers and internet cables simply don’t
Hundreds of cube satellites(Cubesat) will be put into
outer space through which we can access free internet
anywhere in the world
Each satellite receives data streams from a network of
ground stations and transmits that data in a continuous
loop until new content is received.

Space Segment consists of 14 satellites evenly spaced
at a distance of 900km in circular equatorial orbit.
All LEO satellites in orbits below 600km altitude will
come into range of the constellation
The user segment consist of clients who wish to use
the Outernet Service via their mobiles or tablets.
This segment consists of several ground stations
spread around the equator of the earth.
Due to constellation’s equatorial orbit, each of the
satellites will pass every ground station during every
Three potential ground stations have already been
identified: Guiana Space Centre(South America), Broglio
Space Centre(Kenya) and Pusat Remote
A CubeSat is a type of miniaturized satellite for space
It has a volume of exactly one liter (10 cm cube), has a
mass of no more than 1.33 kilograms.
Double or triple configurations are possible. In this
case allowable mass is 2 kg or 3 kg respectively.
It was first developed by California Polytechnic State
University (Cal Poly) and Stanford University in 1999.
The standard 10×10×10 cm cubesat is often called a 1U
meaning one unit.
Cubesats are scalable along only one axis, by 1U
Cubesats such as “2U” Cubesat (20×10×10 cm) and
“3U” Cubesat (30×10×10 cm)can also be made.
With their relatively small size, CubeSats could each be
made and launched for an estimated price of $65,000–
$80,000( 40 lakh - 50 lakh).
This price tag is far lower than most satellite launches.
This has made CubeSat a best option for schools and
universities in their research work across the world.
Cubesats are launched and deployed using a
mechanism called Poly-Picosatellite Orbit
P-POD technique was also developed by
California Polytechnic State University (Cal Poly).
P-PODs are mounted to a launch vehicle and
carry Cubesats into orbit, then deploy them after
proper signal is received from the launch vehicle.
The price of internet data is not affordable to all.
Outernet will offer worldwide access to information to
everyone, including those who today are beyond the
geographical reach of the internet or can’t afford it.
Outernet’s near term goal is to provide the entire world
with broadcasting data, Internet access for everyone.
Wireless connection to the web available for free to
every person in the world.
Outernet will also offer a humanitarian
communications system, relaying public service
transmission during emergencies in places where there
is no access to conventional communication networks
due to natural disasters.
Outernet will use a network of small satellites to
transmit selected internet data- audio, video, text and
applications- to any WiFi enabled device, including
mobile phones, anywhere in the world at no cost.
Anyone with a device will be able to receive the signals,
regardless of connectivity to the regular intervals.
Costly data plans from local telecom operators will no
longer will be a barrier to accessing the information.
Each satellite will broadcast the Internet to phones,
computers and tablets giving billions of people across
the globe free online access.
Benefits of Outernet
Outernet will bring technologies together, provide
standardization and build a genuinely innovative global
Media Development Investment Fund(MDIF) plans to
request NASA to use the International Space Station to
test their technology in September 2014.
Manufacturing and launching of satellite would begin in
If everything goes according to plan, the Outernet
could be here as soon as June 2015.
Citizens of countries like China and North Korea that
have censored online activity could be given free and
