      S
      a
      topic
      this
      week
      I
      have
      decided
      to
     
     
      A
      discuss
      a
      neat
      article
      that
      I
      came
      across
     
    

    
     
      not
      to
      long
      ago
      in
      an
      old
      EDN
      magazine.
     
     
      The
      article
      described
      the
      newest
      in
      upcoming
     
     
      options
      for
      upscale
      cars,
      the
      Global
      Positioning
     
     
      System(GPS).
      GPS
      applications
      are
      already
      in
     
     
      use
      on
      boats,
      airplanes
      and
      trucks,
      and
      geolo-
     
     
      gists
      are
      also
      using
      GPS
      to
      locate
      fault
      lines
      and
     
     
      oil
      deposits.
      GPS
      uses
      24
      satellites
      in
      six
      orbital
     
     
      planes
      each
      with
      an
      orbital
      time
      of
      12
      hours.
     
     
      This
      configuration
      guarantees
      that
      a
      receiver
     
     
      can
      receive
      messages
      from
      four
      different
      satel-
     
     
      lites.
      These
      messages
      contain
      a
      pseudo-random
     
     
      noise
      signal
      consisting
      of
      a
      clock
      time
      and
     
     
      satellite
      orbit
      information
      that
      is
      decoded
      and
     
     
      compared
      to
      a
      receiver-generated
      code.
      When
     
     
      the
      two
      codes
      match
      then
      the
      time
      delay
      from
     
     
      each
      satellite
      to
      the
      receiver
      is
      determined.
      The
     
     
      GPS
      then
      uses
      the
      four
      satellite
      time
      delays
      and
     
     
      orbital
      data
      to
      translate
      the
      geocentric
      coordi-
     
     
      nates
      data
      into
      longitude,
      latitude,
      and
      altitude.
     
     
      Currently
      GPS
      can
      find
      locations
      with
      a
      spheri-
     
     
      cal
      Error
      probability
      of
      about
      15m.
      Pretty
      wild
     
     
      stuff,
      I
      wish
      I
      had
      had
      it
      in
      my
      car
      when
      I
      drove
     
     
      through
      Quebec
      City,
      maybe
      I
      wouldn’t
      have
     
     
      been
      so
      hopelessly
      lost.
      Then
      again
      it
      probably
     
     
      would
      have
      been
      easier
      to
      learn
      what
      East
      and
     
     
      West
      are
      in
      French.
      I
      tried
      to
      think
      up
      a
      good
     
     
      quip
      for
      this
      week
      but
      it
      was
      as
      hopeless
      as
      my
     
     
      tip
      through
      Q.C.
      so
      I
      had
      to
      plagiarize

      dent
      involved
      inviting
      some
      non-university
     
     
      friends
      to
      a
      hockey
      game.
      I
      discovered
      that
      as
      a
     
     
      student
      I
      got
      in
      free,
      nice
      but
      ridiculous.
      My
     
     
      friends,
      however,
      had
      to
      pay
      ten
      dollars
      for
      the
     
     
      two
      of
      them.
      So
      far
      it
      doesn’t
      sound
      too
      bad.
     
    

    
     
      Next
      came
      the
      basketball
      game.
      The
      family
     
     
      ahead
      of
      me
      had
      to
      pay
      $24.00
      to
      get
      in.
      I
      think
     
     
      this
      is
      absurd.
      $3.00
      for
      every
      child
      under
      12
     
     
      and
      $4.00
      for
      every
      child
      over
      that
      age.
     
    

    
     
      The
      taxpayer
      on
      the
      Island
      paid
      dearly
      to
     
     
      build
      the
      Sports
      Complex
      and
      the
      Civic
      Centre
     
     
      and
      pays
      continually
      to
      fund
      the
      University.
      Is
     
     
      this
      how
      we
      repay
      them?
      This
      abuse
      of
      the
     
     
      public
      that
      is
      an
      offence
      to
      fair
      play.
     
    

    
     
      I
      understand
      that
      students,
      like
      myself,
      pay
     
     
      an
      athletic
      fee
      which
      subsidizes
      sports
      events
     
     
      but
      surely
      we
      could
      pay
      a
      dollar
      or
      two
      to
      see
      a
     
     
      game
      if
      this
      would
      help.
     
    

    
     
      Surely
      the
      University
      could
      see
      their
      way
     
     
      clear
      to
      have
      a
      family
      rate
      to
      put
      the
      cost
      of
      these
     
     
      sports
      events
      within
      reach
      of
      ALL
      Islanders.
      I
     
     
      think
      somewhere
      in
      the
      range
      of
      seven
      or
      eight
     
     
      dollars
      per
      family.
     
    

    
     
      The
      present
      system
      ensures
      that
      some
      of
      the
     
     
      people,
      the
      economically
      depressed,
      who
      might
     
     
      most
      benefit
      from
      seeing
      what
      goes
      on
      at
      the
     
     
      University
      (with
      their
      families)
      will
      not.
     
    

    
     
      I
      don’t
      think
      a
      person
      on
      U.I.C.
      or
      welfare
     
     
      will
      be
      paying
      $19.00
      (two
      adults
      and
      three
     
     
      children
      under
      12)
      to
      watch
      a
      basketball
      game.
     
     
      Maybe
      the
      University
      is
      sending
      a
      clear
      mes-
     
     
      sage
      that
      we
      don’t
      want
      ‘‘those
      kind
      of
      people’’
     
     
      at
      our
      games,
      if
      we
      are
      not
      then
      maybe
      we
     
    
   
   
    
     
      should
      initiate
      a
      family
      rate.
      As
      you
      will
      note
      in
     
     
      my
      postscript
      somebody
      decided
      a
      family
      rate
     
     
      for
      booster
      club
      members.
      If
      the

      a

      it
      stands
      to
      reason
      that
     
     
      the
      economically
      disadvantaged
      person
      stand-
     
     
      ing
      at
      the
      door
      to
      a

      game,
     
     
      mouth
      agape,

      year

      children
      could
      use
      a

      rate.
     
    

    
     
      Just
      one
      more
      beef.

      the

      even
      know
      what
      was
      going
      on
      in
      the
      gym!):
     
     
      566-0373
      And
      the
      number
      I
      tried
      first
      (what
     
     
      a
      joke)
      Sports
      Information:
      566-0721.
     
    

    
     
      Maybe
      the
      University
      wouldn’t
      have
      to
      gouge
     
     
      the
      taxpayer
      quite
      so
      much
      if
      they
      promoted
      the
     
     
      product
      a
      bit
      better.
     
    

    
     
      P.S.
      Q93,
      the
      radio
      station
      was
      tuned
      in
     
     
      to
      what
      was
      going
      on.
     
    

    
     
      P.S.S.
      A
      conversation
      with
      a
      sports
     
     
      centre
      staff
      member
      informed
      me
      of
      special
     
     
      family
      rates
      for
      booster
      club
      members,
      very
      —
     
     
      nice,
      and
      the
      dispersal
      of
      a
      quantity
      of
      tickets
      to
     
     
      Island
      schools.
      They
      are
      not
      heartless!
      Perhaps
     
     
      they
      could
      see
      their
      way
      clear
      to
      reduced
      family
     
     
      rates
      at
      the
      door
      and
      I
      would
      feel
      much
      better
     
     
      about
      inviting
      friends
      to
      the
      game,
      even
      my
     
     
      economically
      disadvantaged
      ones.
