Few things about satellites

  1. 1. Guillaume FERY May 2010 Few things I’ve read… About telecommunications, satellites & space applications in our day to day life (a quiet revolution – new trends & applications)
  2. 2. Telecommunications key figures <ul><li>Out of 1000 satellites in space 1/3 are geostationary telecommunications satellites </li></ul><ul><li>50% of all world’s commercial sattelite broadcast television </li></ul><ul><li>Nearly 66% of the European sacpe industry’s revenues came from applicatons </li></ul><ul><ul><li>#1 telecom applications </li></ul></ul><ul><ul><li>#2 positionning </li></ul></ul><ul><ul><li>#3 remote sensing applications </li></ul></ul><ul><li>49% of French Households receive TV through an aerial and n24% by satellite. </li></ul><ul><li>97% of phone communications still go through terrestrial lines. </li></ul><ul><ul><li>Source : CNES France </li></ul></ul>
  3. 3. Imagine a day without satellites … <ul><li>Trucks caught in monster traffic jams </li></ul><ul><li>Blank TV screens </li></ul><ul><li>No seven day weather forecast </li></ul><ul><li>Aircrafts loosing their bearings </li></ul><ul><li>And even … </li></ul><ul><ul><li>No Synchronizing cash dispensers </li></ul></ul><ul><ul><li>Motoway interchanges KO </li></ul></ul>
  4. 4. Satellites + telecoms = an over-expanding range of applications <ul><li>15 years ago, satellite applications were more for experts </li></ul><ul><li>Today, they are meeting end-users in cities and rural areas </li></ul><ul><ul><li>Guiding drivers and tractors </li></ul></ul><ul><ul><li>Assisting practitioners in civil engineering </li></ul></ul><ul><ul><li>Bringing TV and internet into homes </li></ul></ul><ul><ul><li>(and this trend is likely to continue) </li></ul></ul>
  5. 5. Application 1: telemedecine Monitoring and informing the patients, example of the diabetics <ul><li>Major levers : Growing digital divide and increasing lack of healthcare in rural areas </li></ul><ul><li>The idea : a satellite system capable of delivering a full range of services </li></ul><ul><li>Adapted for medical applications in Toulouse (France) to monitor diabetics, disseminate information and provide them with a dedicated TV Channel </li></ul><ul><li>Numerous applications of telemedecine </li></ul>
  6. 6. Application 2: agriculture <ul><li>Why ? satellites aiding integrated farming </li></ul><ul><li>The idea : a tracter fitted with a GPS receiver drives automatically to where it needs to apply fertilizer </li></ul><ul><li>Major benefits </li></ul><ul><ul><li>Farmers van keep closer track of seedling and obtain field level yield maps to,optimize fertilizer inputs (30% less nitrogen) </li></ul></ul><ul><ul><li>Good for the environment : limiting imputs reduces risks of water pollution </li></ul></ul><ul><li>Example : </li></ul>
  7. 7. Application 3: Civil engineering <ul><li>Why ? The construction industry needs high-tech solutions, for example in assembling sections of a bridge deck. </li></ul><ul><li>The idea : in Viaduc de Millau (France) two receivers were set up in the structure. Using GPS readings, the bridges engineers pushed out the deck by a few centimetres per minute. </li></ul><ul><li>Major benefits </li></ul><ul><ul><li>GPS is now used in the construction industry everyday. </li></ul></ul><ul><li>Example : </li></ul>
  8. 8. Application 4: Managing transport <ul><li>Two main applications </li></ul><ul><ul><li>General public </li></ul></ul><ul><ul><li>Civil aviation </li></ul></ul><ul><li>B2C app : GPS can even be connected to the telephone and able to provide commercial relative content to guide the customer. </li></ul><ul><li>Air navigation data need to be spot on. The future European Galileo satellite navigation system will provide a very reliable service. </li></ul><ul><li>Visit : </li></ul>
  9. 9. Trends & new applications <ul><li>Major levers </li></ul><ul><ul><li>Innovation </li></ul></ul><ul><ul><li>Convergence </li></ul></ul><ul><ul><li>Complementarity </li></ul></ul><ul><li>Examples: </li></ul><ul><ul><li>GPS controlled spreading of road salt in winter </li></ul></ul><ul><ul><li>Triple play package (internet+telephone+TV) </li></ul></ul><ul><li>Sometimes, new services come from unexpected applications </li></ul><ul><ul><li>the ground noise into the GPS signal can now be used to analyse map soil moisture. </li></ul></ul>
  10. 10. <ul><li> </li></ul><ul><li> </li></ul><ul><li> </li></ul><ul><li> </li></ul><ul><li> </li></ul><ul><li>Most of the facts and figures here come from a French Magazine ‘CNES Mag » edited by CNES (French national space agency) </li></ul>LINKS and BOOKS Guillaume FERY – May 2010 p
