GOOGLE PROJECT LOON

• Introduction• What is project loon• Working principle of project loon• Technology used• Equipment used• Advantages• Conclusion

INTRODUCTION• Project loon is a research and development project developed

being developed by Google with mission of providing internet access to rural and remote areas.

• A balloon is a flexible bag filled with air or gas.

• The balloon is also considerably used to gather weather information such as atmospheric pressure, temperature, humidity and wind speed.

WHAT IS PROJECT LOON• Google had considered contracting with or acquiring Space

Data Corp., a company that sends balloons carrying small base stations about 20 miles up in the air for providing connectivity.

• Unofficial development of the project began in 2011 under incubation in Google X with a series of trial runs in California’s central valley. The project was officially announced as Google Project Loon on June 2013.

Pilot Experiment• On 16th June 2013, Google began a pilot experiment in New

Zealand where about 30 balloons were launched in coordination with Civil Aviation Authority.

Working principle of project loon• Each super-pressure balloon is massive with a whopping 15-

meter diameter.

• It is made of very thin, very light polyethylene plastic though, so it lifts up the sky easily.

• It is strong enough to lift the flight computer and other electronics. All these are powered by a solar power panel.

User Connectivity• Users of the service connect to the balloon using a special

Internet antenna attached to their building.

• The sign travels through the balloon network from balloon to balloon, then to a ground based station connected to an Internet Service Provider(ISP).

• The system aims to improve communication during natural disasters to affected regions.

Technology used• The small box hangs below the envelope, and looks very

similar to the basket in a hot air balloon.

• It holds electronic devices such as circuit boards, radio antennas, solar panels, batteries, GPS and devices to monitor weather conditions.

• The circuit board controls the overall balloon system and radio antennas are for communication.

Envelopes• Project Loon’s balloon envelopes are made from sheets of

polyethylene plastic and stand fifteen meters wide and twelve meters tall when fully inflated.

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.

Equipment• A small box containing the balloon’s electronic equipment.• This box contains the circuit boards that control the system.• Radio antennas to communicate with other balloons and with

Internet antennas on the ground.

Advantages• Lower cost• Availability of information• Education• Health and Medicine• Use of Renewable energy• Weather surveillance• Collaboration

Conclusion• Project Loon is an ambitious project and the world will highly

benefit from it.

• Project Loon an initiative to help fill in those internet gaps through the use of networked balloons.

• The goal is to provide broadband like internet for the two thirds of the world that doesn’t have access to a reliable internet connectivity by balloon.

• It is still in experimental phase.

STILL CURIOUS?
