The Outernet is a global networking project currently

under development by the Media Development

Investment Fund (MDIF), which is established in 1995.

The Outernet's goal is to provide free access to internet

data through Wi-Fi, made available effectively to all parts

of the world.

Less than 40% of the global population has access to the

wealth of knowledge found on the Internet.

The price of data in many parts of the world continues to be

unaffordable for the majority of global citizens.

In some places, such as rural areas and remote regions, cell

towers and Internet cables simply don't exist.

The primary objective of the Outernet is tobridge the global information divide.

Outernet's Wi-Fi solution works by using hundreds of tiny 10cm

cube-shaped satellites called "cubesats“.

Outernet consists of a constellation of low cost, miniature

satellites in Lower Earth Orbit.

Each satellite receives data streams from a network of ground

stations and transmits that data in a continuous loop until new

content is received.

A CubeSat is a type of miniaturized satellite for space research

with a volume of exactly one liter (10 cm cube), has a mass of

1.33 kilograms.

Double or triple configurations are possible. In this case

allowable mass is 2 kg or 3 kg respectively.

The standard 10×10×10 cm Cubesat is often called a 1U meaning

one unit.

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 40 lakh - 50 lakh.

Cubesats are launched and deployed using a mechanism

called Poly-Pico satellite Orbit Deployer (P-POD).

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.

System Segments

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 orbit.

Three potential ground stations have already been

identified: Guiana Space Centre(South America), Broglio

Space Centre(Kenya) and Pusat Remote Sensing

(Malaysia).

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 exist.

It would allow users to bypass any internet censorship

policies

Outernet's Wi-Fi would ideally benefit areas with no access

to Wi-Fi at all.

The network could also be used as a global notification

system during emergencies and natural disasters, when mobile

base stations and power grids go offline.

Less land and material consumed by not building multiple

ground stations.

Outernet's near-term goal is to provide the entire

world with broadcast data.

The long-term vision includes the addition of two-way

Internet access for everyone for free.

The Outernet, as envisioned, would be one-way-data

would flow from feeders to the satellites which

would broadcast to all below for free.
