3. WHAT IS PROJECT LOON?
Project loon is a network of balloons travelling on edge
of space, designed to connect people in rural and
remote areas.

4. HISTORY
• It also started to launch its own cheap biodegradable latex weather
balloons and provide private networks to truckers and oil companies.
• One balloon with a weight of 1.5 kg, a size of 7.6 m (25ft) when fully
inflated, can cover a 670 km diameter coverage circle below.
• It currently covers only Texas, New Mexico and Louisiana .

5. 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 tester’s will be used to
refine the technology and shape the next phase of
Project Loon.

6. EUIPMENT
•ENVELOPE
• SOLAR PANELS
• PAYLOAD

7. 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.
SOLAR PANELS:
Each unit’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.
PAYLOAD:
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

8. TECHNOLOGY
•SOLAR AND BATTERY TECHNOLOGY
• ALGORITHMIC CONTROL
• WIRELESS MESH NETWORKING
•ISM BANDS

9. WHERE LOON SITUATED
• Loon balloon float in the
stratosphere at 20km
altitude.

10. 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

12. 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
• Three radio transceivers.
balloon-to-balloon communications.
balloon-to-ground communication.
third for backup.
• The balloons use antennas equipped with specialized radio frequency
technology. Project Loon currently uses ISM bands that are available for
anyone to use.

13. HOW LOON CONNECTS

15. ADVANTAGES
•GPS expansion
•Weather surveillance
•Cheaper internet
•3G speed

16. DISADVANTAGES
•Cost.
•Maintenance.
•Balloon can work few weeks only.

17. CONCLUSION
• Two out of three people on earth do not have internet access
• Project loon is an ambitious project and the world will highly benefit
from it.
• By using this project we can give the internet access to many rural
areas.
• Its is still in experimental phase..
