Satellites play a key role in telecommunications and many applications in everyday life. Over 1/3 of satellites are used for telecommunications and nearly 66% of European space industry revenues come from telecom applications. Satellites enable applications like telemedicine to monitor diabetics, precision agriculture using GPS, and construction projects using GPS for assembly. New trends include integrating satellite navigation into vehicles and triple play packages combining internet, phone and TV.

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.

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 : http://www.infoterra-group.com

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 : http://en.wikipedia.org/wiki/Millau_Viaduct

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 : http://www.esa.int/esaNA/galileo.html

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.
