  1. 1. Presented By:- Rajanish Kumawat 10ESOEC092 4TH YEAR, VIIITH SEM A Seminar On:-
  3. 3.  Outernet is a global network of cube satellites (Cubesats) broadcasting Internet data to all over the world.  Outernet project is currently under development by a US organization Media Development Investment Fund (MDIF).  Outernet’s goal is to provide free access to internet data through Wi-Fi, made available effectively to the all part of the world.  It is a modern version of shortwave radio, or BitTorrent from space.
  4. 4.  There are more computing devices in the world than people, yet less than 40% of the global population has access to the wealth of knowledge found on the internet.  In some places, such as rural areas and remote regions, cell towers and internet cables simply don’t exist.
  5. 5.  Hundreds of cube satellites(Cubesat) will be put into outer space through which we can access free internet anywhere in the world  Each satellite receives data streams from a network of ground stations and transmits that data in a continuous loop until new content is received.
  6. 6. 1. Space Segment 2. Ground Segment and 3. User Segment Fig:- Interfacing Between System Segments
  7. 7.  Space Segment consists of 14 satellites evenly spaced at a distance of 900km in circular equatorial orbit.  All LEO satellites in orbits below 600km altitude will come into range of the constellation User Segment  The user segment consist of clients who wish to use the Outernet Service via their mobiles or tablets.
  8. 8.  This segment consists of several ground stations spread around the equator of the earth.  Due to constellation’s equatorial orbit, each of the satellites will pass every ground station during every orbit.  Three potential ground stations have already been identified: Guiana Space Centre(South America), Broglio Space Centre(Kenya) and Pusat Remote Sensing(Malasia).
  9. 9.  A CubeSat is a type of miniaturized satellite for space research.  It has a volume of exactly one liter (10 cm cube), has a mass of no more than 1.33 kilograms.  Double or triple configurations are possible. In this case allowable mass is 2 kg or 3 kg respectively.  It was first developed by California Polytechnic State University (Cal Poly) and Stanford University in 1999. Specifications:-
  10. 10.  The standard 10×10×10 cm cubesat is often called a 1U meaning one unit.  Cubesats are scalable along only one axis, by 1U increments.  Cubesats such as “2U” Cubesat (20×10×10 cm) and “3U” Cubesat (30×10×10 cm)can also be made. Specifications:-

  12. 12.  With their relatively small size, CubeSats could each be made and launched for an estimated price of $65,000– $80,000( 40 lakh - 50 lakh).  This price tag is far lower than most satellite launches. This has made CubeSat a best option for schools and universities in their research work across the world. Specifications:-
  13. 13.  Cubesats are launched and deployed using a mechanism called Poly-Picosatellite Orbit Deployer (P-POD).  P-POD technique was also developed by California Polytechnic State University (Cal Poly).  P-PODs are mounted to a launch vehicle and carry Cubesats into orbit, then deploy them after proper signal is received from the launch vehicle.
  14. 14.  The price of internet data is not affordable to all.  Outernet will offer worldwide access to information to everyone, including those who today are beyond the geographical reach of the internet or can’t afford it.  Outernet’s near term goal is to provide the entire world with broadcasting data, Internet access for everyone. For free.
  15. 15.  Wireless connection to the web available for free to every person in the world.  Outernet will also offer a humanitarian communications system, relaying public service transmission during emergencies in places where there is no access to conventional communication networks due to natural disasters.  Outernet will use a network of small satellites to transmit selected internet data- audio, video, text and applications- to any WiFi enabled device, including mobile phones, anywhere in the world at no cost.
  16. 16.  Anyone with a device will be able to receive the signals, regardless of connectivity to the regular intervals.  Costly data plans from local telecom operators will no longer will be a barrier to accessing the information.  Each satellite will broadcast the Internet to phones, computers and tablets giving billions of people across the globe free online access. Benefits of Outernet
  17. 17.  Outernet will bring technologies together, provide standardization and build a genuinely innovative global platform.  Media Development Investment Fund(MDIF) plans to request NASA to use the International Space Station to test their technology in September 2014.  Manufacturing and launching of satellite would begin in early 2015.
  18. 18.  If everything goes according to plan, the Outernet could be here as soon as June 2015.  Citizens of countries like China and North Korea that have censored online activity could be given free and unrestricted cyberspace.
