so Joe opted for land transport but he found it
slow and unreliable, however cheap...

or maybe?

Bad experience with satellites?
Expensive, unreliable, confusing or simply I
dont know why I would need one?

SISTER Overview

• 10.5M Integrated Project co-funded by DG
  Enterprise Industry (FP6)
• 3 years project, started in Nov. 2006
• SISTER promotes the integration of satellite and
  terrestrial communications with GALILEO to enable
  mass-market take-up by road transport
  applications.

Chosen applications
Satellite Narrowband bidirectional data
transmission (SND)
Satellite Data Broadcasting (SDB)

• Safety Security Services
• eCall
• Theft detection
• Remote Vehicle Diagnostic
• PAYD insurance
• Road User Charging
• Commercial Vehicles Services
• Fleet Management systems

• Vehicle Navigation Service
• Digital Maps Update
• Traffic and weather information

13
Why Satellite ?

• Provides back-up communications capability,
  closing the coverage gaps of terrestrial network
• Very efficient broadcast mode
• Coverage Pan-European solution, rural areas
• Initiating communication/ authentication/ OBU
  interogation
• Cost effective for large number of customers
• No roaming necessary
• Enforcement
• Minimal infrastructure
• Distribution of traffic over various
  communication platforms
• Premium services

S-band

• S-band
• Proximity to UMTS (3G) gives opportunity to
  modify existing chipsets and integrate S-band
  with existing handhelds and other devices
• 2 x 30MHz reserved for mobile satellite services
  to be awarded in Q2 2009
• Available in 27 EU member states interoperable
  and scalable solution
• Better penetration in built-up areas
• No roaming
• 1st S-band satellite available in early 2009

Demonstrations - eCall

• Communication media tests
• in different environments (cities, rural,
  hills, forests)
• in different weather conditions
• in areas favoured by specific communications
  media

23
Demonstrations Map Updates
Concept feasibility test
Content delivery time

• Different environments

• Driving behaviours

• Files with regular priority and alerts

Integrated Demonstration
25
Real Time Kinematics
OBJECTIVE demonstrate that satellite
communications can support real-time carrier
phase positioning of an unlimited number of
users, at the level of a few centimetres. Emphasi
s on high accuracy, low bandwidth, and unlimited
number of users at the same time.
26
Authentication and Reconfiguration
Authentication demonstration will involve the
continuous satellite broadcast of digital
signatures to authenticate the veracity of GPS
navigation data. The demonstration will include
the broadcast of signatures and the associated
information/algorithms defining their
use. Reconfiguration part will demonstrate the
reconfiguration of a GNSS receiver via satellite
communications upgrading the functionality and
performance of the GNSS user terminal.

Added values of satellite-based RUC(broadcast)

• In Germany, 600.000 OBUs for toll collect are
  currently in use (trucks gt 12 t)
• Problems
• Tariff data updates in 2008 required till a fixed
  date (Legislature).
• Each OBU has to ask at the BOS (Back Office
  System) for new data
• Tariff data has to be downloaded minimum 600.000
  times
• Congestion at the BOS server can be expected
• Time-critical solution via GPRS
• During start phase, each OBU asks BOS for new
  data.
• Each Monday morning a lot of trucks start at
  nearly the same time. ? Congestion at the BOS
  server
• Solution in the current implementation (Toll
  Collect Germany) random delay of data requests
  during start phase is used.
• Satellite broadcast can
  avoid such problems
