  precise ephemeris can be repeated. The following example demonstrates the
  use of precise ephemerides.

  <subsection|Emulating Standard Positioning Service (SPS) Performance>

  By default, <with|font-family|tt|rinexpvt> will attempt to form the best
  possible position for each epoch of observation. If dual frequency
  observations are applied, they are used. If for a single epoch, only C/A
  observations are available, then it is used. In order to perform solutions
  using only C/A, the <with|font-family|tt|-s> switch is available. The
  following is a demonstration of this switch.

  <with|prog-language|shell|prog-session|default|<\session>

  <subsection|Emulating Precise Positioning Service (PPS) Performance>

  Similar to the option described in the previous subsection, there is an
  option to limit the solutions of <with|font-family|tt|rinexpvt> to those
  strictly derived from dual frequency observations. The following session
  demonstrates this switch.

  <with|prog-language|shell|prog-session|default|<\session>
    <\input|shell] >
      rinexpvt -o usno0200.05o -n brdc0200.05n -m usno0200.05m -d \

  <subsection|Customizing the Epoch Format>

  The GPSTk library supports conversion among a number of time formats. This
  conversion ability is provided to the end user of
  <with|font-family|tt|rinexpvt> in the form of the <with|font-family|tt|-t>
  command line switch and its argument, a string describing the time format.
  The GPSTk documentation to DayTime's printf method contains a full list of
  specifiers that can be used within the time format string. The following
  table summarizes some of these options.

  \;

  <\with|par-mode|center>
    <tabular|<tformat|<table|<row|<cell|%Y>|<cell|Four digit
    year>>|<row|<cell|%y>|<cell|Year modulo 100>>|<row|<cell|%m>|<cell|Month
    number>>|<row|<cell|%b>|<cell|Month name>>|<row|<cell|%d>|<cell|Day of
    month>>|<row|<cell|%S>|<cell|Second of minute>>|<row|<cell|%F>|<cell|Full
    GPS week>>|<row|<cell|%Z>|<cell|Z count>>|<row|<cell|%g>|<cell|Seconds of
    week>>|<row|<cell|%j>|<cell|D<\float|float|tbh>
      <big-table||>
    </float>ay of year>>|<row|<cell|%s>|<cell|Seconds of
    day>>|<row|<cell|%Q>|<cell|Modified Julian Date>>>>>
  </with>

  <\with|par-mode|center>
    Table. Time Format Specifiers
  </with>

  \;

  In the following example we see how to apply the format specifiers in the
  form of a string.

  <with|prog-language|shell|prog-session|default|<\session>
    <\input|shell]>
      rinexpvt -o usno0200.05o -n brdc0200.05n -m usno0200.05m -t "%F %g"\
