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

    • Most of the facts and figures here come from a French Magazine ‘CNES Mag » edited by CNES (French national space agency)
