title: Simulate Low and Hight Gps Accuracy
body: <p>I did a .gpx file to simulate a route on IOS simulator, now i wanna simulate the horizontal accuracy how I can do this?</p>
  
  <p>as follow is an excerpt of my .gpx file:</p>
  
  <pre><code>&lt;?xml version="1.0"?&gt;
  &lt;gpx&gt;
      &lt;wpt lat="-23.772830" lon="-46.689820"/&gt; //how add horizontal accuracy 7 meters for example
      &lt;wpt lat="-23.774450" lon="-46.692570"/&gt; //and here horizontal accuracy of 2 metters for example
      &lt;wpt lat="-23.773450" lon="-46.693530"/&gt; //and here 19 meters
  &lt;/gpx&gt; 
  </code></pre>
  
  <p>if I run all gps points return horizontal accuracy of 5 meters, I can change this otherwise.</p>
