Project Loon is a network of balloons travelling in the stratosphere designed to connect people in rural and remote areas. The project began development in 2011 at Google X labs and was announced officially in 2013. An initial pilot test was conducted in 2013 in New Zealand using 30 balloons launched from the South Island to test the technology. The balloons float in the stratosphere and are steered by rising and descending to altitudes with winds moving in the desired direction. People on the ground connect to the balloon network using a special antenna. The signal bounces between balloons and then connects to the global internet.

2. What is project loon
 Project loon is a network of balloons travelling on the edge of space,
designed to connect people from rural and remote areas.
 In 2011 the unofficial development of project began under Google X labs.
 On 14 June 2013 Google announced this project as an official project.

4. THE PILOT TEST
 Project Loon starts in June 2013 with an experimental pilot in New
Zealand. A small group of Project Loon pioneers will test the technology in
Christchurch and Canterbury.
 30 balloons, launched from New Zealand’s South Island.
 The experience of these pilot testers will be used to refine the technology
and shape the next phase of Project Loon.

6. THE TECHNOLOGY
 Project Loon balloons float in the stratosphere, twice as high as airplanes and
the weather.
 They are carried around the Earth by winds and they can be steered by rising
or descending to an altitude with winds moving in the desired direction.
 People connect to the balloon network using a special Internet antenna
attached to their building.
 The signal bounces from balloon to balloon, then to the global Internet back
on Earth.
.

8. Stratosphere
 Situated between 10 km and 60 km altitude on the edge of
space.
 Air pressure is 1% of that at sea level.
 Thinner atmosphere offers less protection from the UV
radiation and temperature caused by the sun’s rays.

9. HOW LOON MOVES
 Winds in the stratosphere are generally steady and slow-moving at between
5 and 20 mph, and each layer of wind varies in direction.
 Project Loon uses software algorithms to determine where its balloons need
to go, then moves each one into a layer of wind blowing in the right
direction.
 By moving with the wind, the balloons can be arranged to form one large
communications network

11. HOW LOON IS DESIGNED
 ENVELOPE
 SOLAR PANELS
 EQUIPMENT

13. ENVELOPE
 Project Loon’s balloon envelopes are made from sheets of
polyethylene plastic and stand fifteen meters wide by twelve
meters tall when fully inflated.
 A parachute attached to the top of the envelope allows for a
controlled descent and landing whenever a balloon is ready
to be taken out of service.

14. SOLAR PANELS
 Each balloon’s electronics are powered by an array of solar panels that sits
between the envelope and the hardware.
 In full sun, these panels produce 100 Watts of power - enough to keep the
unit running while also charging a battery for use at night.
 By moving with the wind and charging in the sun, Project Loon is able to
power itself using only renewable energy sources.

15. EQUIPMENT
 A small box containing the balloon’s electronic equipment .
 This box contains circuit boards that control the system .
 Radio antennas to communicate with other balloons and with Internet
antennas on the ground .
 And batteries to store solar power so the balloons can operate during the
night .

16. HOW LOON CONNECTS
 Each balloon can provide connectivity to a ground area
about 40 km in diameter at speeds comparable to 3G.
 Each balloon is equipped with a GPS for tracking its
location.

17. HOW LOON CONNECTS
 Three radio transceivers
 balloon-to-balloon communications.
 balloon-to-ground communication.
 The balloons use antennas equipped with specialized radio frequency
technology.

19. Advantages
 Easy to use
 Speed
 Increase internet usage

20. Disadvantages
 Cost
 Maintenance
