4. What is the need?
Two out of every three people on earth do not have access to internet.
Project loon is the network of balloons travelling on the edge of the space,
designed to connect people in remote and rural areas to internet, help fill
the coverage gaps, and bring people back online after disasters.

5. About the balloon technology
Balloons float in the stratosphere at a height twice as that of a airplane.
Project Loon balloons are designed and manufactured at scale to survive
the conditions in the stratosphere, where winds can blow over 100 km/hr
and the thin atmosphere offers little protection from UV radiation and
dramatic temperature swings which can reach as low as -90°C. Made
from sheets of polyethylene, each tennis court sized balloon is built to last
more than 100 days in the stratosphere before returning to the ground in
a controlled descent.

6. Contd….
Project Loon has taken the most
essential components of a cell
tower and redesigned them to be
light enough and durable enough
to be carried by a balloon 20 km
up in the stratosphere. All the
equipment is highly energy-
efficient and is powered entirely
by renewable energy - with solar
panels powering daytime
operations and charging a
battery for use during the night.

7. Launching of Balloons
Custom-built Auto launchers are designed to launch Loon balloons safely
and reliably at scale. Huge side panels provide protection from the wind
as the balloon is filled and lifted into launch position, and then the crane
is pointed downwind to smoothly release the balloon up into the
stratosphere. Each crane is capable of filling and launching a new balloon
into the Loon network every 30 minutes.

8. Navigating the Balloons
In the stratosphere winds are stratified, and each layer of wind varies in
speed and direction. To get balloons to where they need to go The
positioning of the Loon fleet is adjusted and controlled in real-time from
Loon Mission Control, using a combination of automatic planning
algorithms and human oversight. By moving with the wind, the balloons
can be arranged to provide coverage where it’s needed.

9. Equipment
TRANSCEIVERS
transmit connectivity from ground
stations, across balloons, and back
down to users' LTE phones.
SOLAR PANEL
power the equipment during the
day and charge an onboard
battery to allow for nighttime
operation.
PARACHUTE
automatically deploys at the end of
the balloon flight for a safe descent
back to Earth.
FLIGHT CAPSULE
contains the brains of the system
for command and control of the
Loon balloon.

10. Connecting to Balloons
Loon balloons act as floating cell towers, allowing local
telecommunications companies to extend their coverage into areas
that are currently unserved. In user tests, it is observed that Loon
gives Internet speeds similar to that of current LTE/4G networks that
many people get on their phones today.

11. Working
Project Loon is partnering with telecommunications companies to
extend connectivity into rural and remote areas so that people
everywhere will be able to access the Internet directly from their
phones and other LTE-enabled devices. Wireless internet signal is
transmitted up to the nearest balloon from our telecommunications
partner on the ground, relayed across the balloon network, and then
sent back down to people in rural and remote areas. Each balloon has
a coverage area of 5000 square kilometers and can serve thousands
of subscribers.

12. Recovery of Balloons
The Project Loon team tracks the location of every balloon using GPS,
coordinating directly with the local air traffic control to bring each one safely to
ground targeting sparsely populated areas. When a balloon is ready to be
taken out of service, the lift gas keeping the balloon aloft is released and the
parachute deploys automatically to bring the balloon to the ground in a
controlled descent. The recovery teams then collect the equipment for reuse

13. The Pilot Test
 Project Loon began with a pilot test in June 2013, when
thirty balloons were launched from New Zealand’s South
Island and beamed Internet to a small group of pilot
testers.

14. Responsibility towards Environment
 Google is working to guide all balloons to collection points upon
descent, so that they can be reused, recycled, or responsibly
disposed off.
 When balloons do not make it to one of these collection points,
Google sends a recovery team out to collect them.
 The balloons’ electronics are entirely solar powered.
 Google is working to make the stratospheric wind data ,collected
by balloons, available to the environmental science community
so it can be used to improve weather and climate models.

15. Project Loon in India
 Google might be conducting pilot test for Project loon in
India near the end of the year 2016.
 The location of the pilot is expected to be in Andhra
Pradesh or Maharashtra.
 The National Informatics Centre (NIC) has been tasked
with the job of zeroing in on the location and other
requirements for the pilot.
