Project Loon is an experimental project by Google to provide internet access to rural and remote areas using balloons floating in the stratosphere. In June 2013, Project Loon launched a pilot program in New Zealand using 30 balloons to test the technology and refine the system. The balloons can beam internet signals to users on the ground and move between wind layers in the stratosphere to stay positioned over users. They are powered by solar panels and can provide connectivity over an area of about 40 km in diameter.

- 1. Guided by :- Dr. V.K. Patle Ms. Swarnima Shrivastava
- 2. 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.
- 4. 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.
- 7. Stratosphere 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
- 8. 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.
- 10. HOW LOON IS DESIGNED ENVELOPE SOLAR PANELS EQUIPMENT
- 12. 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.
- 13. 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.
- 14. 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 .
- 15. 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
- 16. Three radio transceivers. The balloons use antennas equipped with specialized radio frequency technology. Project Loon currently uses ISM bands that are available for anyone to use. balloon-to-balloon communications. balloon-to-ground communication. third for backup
- 18. ISM BANDS The industrial, scientific and medical (ISM) radio bands . Radio bands reserved internationally for the use of radio frequency (RF) energy for industrial, scientific and medical purposes other than communications.
- 19. Advantages Easy to use. Speed. Increasing Internet usage.
- 20. Disadvantages Cost. Maintenance. Balloon can work for few week only.
