Transcript of Copy of Project Loon

HOW LOON IS DESIGNED
A Project Loon balloon consists of three main parts:
Envelope
Solar Panels
Equipment
THE PILOT TEST
Project Loon began in June 2013 with an experimental pilot in New Zealand.
A small group of Project Loon pioneers tested the technology in Christchurch and Canterbury.
Thirty balloons, launched from New Zealand’s South Island, beamed Internet to a small group of pilot testers.
The experience of these pilot testers is now being used to refine the technology and shape the next phase of Project Loon.
CONCLUSION
This project is still experimental.
Google believes it will be a feasible, cost-effective and realiable project.
They are finding partners for the next stage of the project.

PROJECT LOON
BALLOON-POWERED INTERNET FOR EVERYONE
WHAT IS PROJECT LOON?
Project Loon is a network of balloons traveling on the edge of space, designed to connect people in rural and remote areas, help fill coverage gaps, and bring people back online after disasters.
THE TECHNOLOGY
HOW LOON MOVES
HOW LOON CONNECTS
ENVELOPE
SOLAR PANELS
EQUIPMENT
Travel around 20 km above the Earth’s surface in the stratosphere.
Winds in the stratosphere are generally steady and slow-moving at between 8 and 32 km/h, and each layer of wind varies in direction and magnitude.
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.
STRATOSPHERE
Engineering challenges:
Air pressure is 1% of that at sea level.
Temperatures are around -50°C.
A thinner atmosphere offers less protection from the UV radiation.

Advantages:
Steady winds.
Above weather events, wildlife, and airplanes.
Each balloon can provide connectivity to a ground area about 40 km in diameter at speeds comparable to 3G.
For balloon-to-balloon and balloon-to-ground communications, the balloons use antennas equipped with specialized radio frequency technology.
Project Loon currently uses ISM bands (specifically 2.4 and 5.8 GHz bands) that are available for anyone to use.
Inflatable part of the balloon, of Helium.
Material: sheets of polyethylene plastic.
Dimensions: fifteen meters wide by twelve meters tall when fully inflated.
Can float for more than 100 days.
About the size of a card table.
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.
This box (10kg) 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.
They 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.
WHY DID I CHOOSE PROJECT LOON?
Innovative way of internet communication
How do balloons in space can give connectivity to some parts of the World?
Ambitious and feasible project
OBJECTIVES/CONSTRAINTS
Objectives:
Give Internet access to rural and remote areas.
Globalization.
Bring people back after natural disasters.
Constraints:
Legal regulations of every different country.
Unexpected descending of balloons.
Costs of development and investigation.
