The Outernet project aims to provide free global access to internet data through low-cost cube satellites and Wi-Fi. It would consist of a constellation of 14 small satellites in low Earth orbit that receive and broadcast data to users worldwide. This would help bridge the digital divide as less than 40% of the global population currently has internet access, especially in rural and remote areas where infrastructure does not exist. The goal is to eventually provide two-way internet access for all.
Outernet ready to present ppt
- 2. οThe Outernet is a global networking project currently under development by the Media Development Investment Fund (MDIF), which is established in 1995. οThe Outernet's goal is to provide free access to internet data through Wi-Fi, made available effectively to all parts of the world.
- 3. ο Less than 40% of the global population has access to the wealth of knowledge found on the Internet. οThe price of data in many parts of the world continues to be unaffordable for the majority of global citizens. οIn some places, such as rural areas and remote regions, cell towers and Internet cables simply don't exist. The primary objective of the Outernet is to bridge the global information divide.
- 4. ο Outernet's Wi-Fi solution works by using hundreds of tiny 10cm cube-shaped satellites called "cubesatsβ. ο Outernet consists of a constellation of low cost, miniature satellites in Lower Earth Orbit. ο Each satellite receives data streams from a network of ground stations and transmits that data in a continuous loop until new content is received.
- 5. οA CubeSat is a type of miniaturized satellite for space research with a volume of exactly one liter (10 cm cube), has a mass of 1.33 kilograms. οDouble or triple configurations are possible. In this case allowable mass is 2 kg or 3 kg respectively.
- 6. ο The standard 10Γ10Γ10 cm Cubesat is often called a 1U meaning one unit. ο Cubesats such as β2Uβ Cubesat (20Γ10Γ10 cm) and β3Uβ Cubesat (30Γ10Γ10 cm)can also be made. ο With their relatively small size, Cubesats could each be made and launched for an estimated price of 40 lakh - 50 lakh.
- 7. ο Cubesats are launched and deployed using a mechanism called Poly-Pico satellite Orbit Deployer (P-POD). ο P-POD technique was also developed by California Polytechnic State University (Cal Poly). ο 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.
- 8. 1. Space Segment 2. Ground Segment and 3. User Segment Fig:- Interfacing Between System Segments
- 9. ο Space Segment consists of 14 satellites evenly spaced at a distance of 900km in circular equatorial orbit. ο All LEO satellites in orbits below 600km altitude will come into range of the constellation οThe user segment consist of clients who wish to use the Outernet Service via their mobiles or tablets.
- 10. ο This segment consists of several ground stations spread around the equator of the earth. ο Due to constellationβs equatorial orbit, each of the satellites will pass every ground station during every orbit. ο Three potential ground stations have already been identified: Guiana Space Centre(South America), Broglio Space Centre(Kenya) and Pusat Remote Sensing (Malaysia).
- 12. ο 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. ο In some places, such as rural areas and remote regions, cell towers and internet cables simply donβt exist.
- 13. οIt would allow users to bypass any internet censorship policies ο Outernet's Wi-Fi would ideally benefit areas with no access to Wi-Fi at all. οThe network could also be used as a global notification system during emergencies and natural disasters, when mobile base stations and power grids go offline. οLess land and material consumed by not building multiple ground stations.
- 14. οOuternet's near-term goal is to provide the entire world with broadcast data. οThe long-term vision includes the addition of two-way Internet access for everyone for free.
- 15. οThe Outernet, as envisioned, would be one-way-data would flow from feeders to the satellites which would broadcast to all below for free.
