Brief history of electronic navigation and location l.jpg
BRIEF HISTORY OF ELECTRONIC NAVIGATION AND LOCATION

  • Radio Navigation and Location

    • Air Navigation

  • Radio Navigation Beacons

    • Aeronautical

    • Maritime (Decca/LoranC)

    • Terrestrial


History of satellite 1 l.jpg
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


History of satellite 2 l.jpg
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


Satellite developments l.jpg
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


Overview of positioning technologies l.jpg
OVERVIEW OF POSITIONING TECHNOLOGIES

  • Terrestrial Radio Beacons

  • GPS

  • GSM

  • Satellite

  • Transponder


Terrestrial radio l.jpg
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)


Securicor datatrack l.jpg
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


Slide11 l.jpg
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


Differential gps l.jpg
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

Russians selling navigational jamming device

BY BOB BREWIN

ALEXANDRIA, Va. -- A recently developed Russian jamming device that can knock out satellite navigation system signals has been sold to numerous countries, opening the possibility that terrorists could seriously disrupt the system that ships and aircraft use to navigate, according to government officials.

Global Positioning Systems Fail Todayby Dave Murphy

Ninety-Five Thousand Japanese drivers may have to leave their cars at home, starting today.

Pioneer Electronic Corp., a vendor of Global Positioning System (GPS) devices, had started to receive hundreds of calls for assistance from owners of its products when the GPS display screens started to go blank or the units froze up.


Slide15 l.jpg
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


Leo satellites l.jpg
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




Requirements for bearer network l.jpg
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


Examples of bearer l.jpg
EXAMPLES OF BEARER

Coverage, Cost and Capacity

  • RAM Mobile Data

  • Vodafone Value Added and Data Services (PAKNET)

  • GSM SMS

  • Securicor Datatrak

  • PAMR

  • Dolphin

  • Private


Business benefits l.jpg
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


Emergency services l.jpg
