INTRODUCTION
Typical AVL System
4
BRIEF HISTORY OF ELECTRONIC NAVIGATION AND
LOCATION

• Radio Navigation and Location
• Air Navigation
• Radio Navigation Beacons
• Aeronautical
• Maritime (Decca/LoranC)
• Terrestrial

5
HISTORY OF SATELLITE (1)

• Sputnik launched in 1957
• US Navy Transit Satellite Network
• Operational on Polaris Submarines in 1964
• Commercially available in 1967
• Accuracy to 160 metres - measures Doppler Shift
• Must be nearly Stationary and update only every
  40 mins
• Atomic Clocks

6
HISTORY OF SATELLITE (2)

• 1973 US Navy USAF combined programs
• 1978 First two Navstar Satellites launched
• Constellation operational in June 95
• At least 24 satellites operational at a time
• Further enhancements to GPS Planned

7
SATELLITE DEVELOPMENTS

• EC recommendation to develop Galileo
• an independent but GPS compatible 2bn Satellite
  system
• May 98 US Naval Academy discontinued courses on
  stellar navigation

8
OVERVIEW OF POSITIONING TECHNOLOGIES

• Terrestrial Radio Beacons
• GPS
• GSM
• Satellite
• Transponder

9
TERRESTRIAL RADIO

• Network of fixed basestations
• LF propagation
• Number bases
• Vehicle Unit calculates position and passes data
  back to control point
• Requires communications e.g. UHF radio
• Coverage Issues (Beacon / Bearer)

10
SECURICOR DATATRACK

• In 1985 Securicor Datatrack looked to increase
  protection and management of its Cash in
  Transit fleet
• Location to within 50 metres
• Protection from Interception and Corruption
• By 1990 over 19M invested in UK Network
• 14 LF Beacons
• Dedicated UHF Band Network

11
GPS

• Global Positioning System
• Primarily Military System
• Run by US DOD
• Selective Availability
• Civilian accuracy typically 100m
• Requires view of several satellites
• Problem in cities

12
DIFFERENTIAL GPS

• Measures offset at fixed reference location
• Broadcast to Vehicle to Give Accurate Remote
  Location
• corrections broadcast by various carriers
• use bearer network to send corrections
• Post-processed at Host
• Accuracy of about 5 metres

13
GPS RESILENCE
14
GPS RESILENCE (2)
15
GSM

• Cell Location
• Identification of Basestation
• Accuracy dependent upon Cell Size
• Cursor
• Series of fixed GSM receivers
• Handset software u/g
• Compares two signals and calculates position
• Accuracy within 125m

16
LEO SATELLITES

• Commercial LEO Services
• Still building network
• Low Cost Messaging
• Containers
• Remote Metering
• Subscriber Unit offer location to approx 1Km by
  measuring Doppler shift

17
ORBCOM SYSTEM

NETWORK COMPARISON
19
REQUIREMENTS FOR BEARER NETWORK

• Capacity depends upon the number of vehicles and
  the position refresh rate
• On board unit must have intelligence to filter
  out and reduce transmissions
• Report by exception
• Stationary
• Can also be used for other services e.g. operator
  status update

Coverage, Capacity and Cost
20
EXAMPLES OF BEARER

• RAM Mobile Data
• Vodafone Value Added and Data Services (PAKNET)
• GSM SMS
• Securicor Datatrak
• PAMR
• Dolphin
• Private

21
BUSINESS BENEFITS

• Little Business Benefit in Location Alone
• Vehicle location display needs map overlay
• Can allow GSM Operators to offer Value Added
  Services
• Key is the Application
• At most basic visual tracking - map display
  overlaid with vehicle locations
• Advanced systems perform workflow management

Real Benefits come from the application
22
EMERGENCY SERVICES

• Ambulance
• RBA to cut Emergency response times by 2 mins
• Response to new Goverment standards
• Confirmation of message delivery

23
TRANSPORT

• 1M contract for 500 installations
• maximise trailer and load efficiencies
• reduced fuel consumption
• internet tracking

24
BUS SERVICES

• Belgian Bus
• dynamic timetable
• download location
• upload pick-up and drop-off points
• Birmingham Centro
• real time information display
• roadside beacons
• initial results 27 increase in passenger
  journeys
• Multi-operator routes

25
UK ELECTRICITY COMPANYFOCUS ON BUSINESS DRIVERS

• Drive for profit
• Improved workforce management
• Competition in energy supply
• Pressure from Industry Regulator
• Improvement in customer services
• Core network reliability

26
UK UTILITY COMPANYFOCUS ON BUSINESS DRIVERS

• Customer Service
• Fault restoration times
• Business Efficiency
• Asset management
• Work management
• Cost monitoring

27
TELEMATICS GLOBAL MARKET

• Integration of Vehicle Control and Monitoring
  Systems with Location Tracking Devices and
  Wireless Telecommunications
• Strategis Group estimates that more that 1.2
  million vehicles will be fitted Telematics
  (currently estimated 56,000)
• Estimate 430,000 commercial vehicles fitted with
  AVL
• Growth on consumer market will drive down
  hardware costs. Market worth 8.4bn by 2011?

28
OTHER BUSINESS DRIVERS

• E911 Directive in US
• development of new positioning systems
• Will drive down costs of GSM based location
