I guess most of you already know but just for who don't..

Location from web browser:
#Gives the coordinates of the nearest Internet server respondent is connected to when survey start.
#Respondent will get a prompt in his browser which he has to confirm only then location will get captured.
#This approach will work even if device do not have GPS like laptop / desktop etc.

Location GPS(eg In Mazi offline application ):
#Capture coordinate using mobile GPS system.
#Highly precise
#No internet connectivity required.

It is very frequent requirement CAPI survys to capture GPS location the moment Interview starts. Clients wants it to confirm that interviewers and doing genuine interview.

If you are talking about the OfflineSurveys GPS location tracking feature, that is pretty simple to set up:
  1. Go to www.offlinesurveys.com/add-android-multimedia-question
  2. Download the "GPS location tracking" question/LSQ file from there.
  3. Import the LSQ file at your survey (this can be done when creating a new question)
  4. Activate the survey and cache the survey for offline usage
That survey should now include the GPS location tracking feature.

"Doesn't work" is not an appropriate error description.
- Are there any error messages?
- Which Limesurvey version do you use?
- Which OfflineSurveys version do you use?
- Did you edit the downloaded question? I just tested it and it worked fine for my at the OfflineSurveys app.

What LimeSurvey version are you using?

Can you attach an export (.lss) of a small sample survey?

Try this for the respective scripts:

Code:
<script type="text/javascript" charset="utf-8">
 
  $(document).on('ready pjax:scriptcomplete',function(){
 
    // Identify this question
    var q1ID = '{QID}';
    var q1 = $('#question'+q1ID);
 
    function getGPS() {
      if (navigator.geolocation) {  
        navigator.geolocation.getCurrentPosition(showGPS, gpsError);
      } else {  
        $('input.text', q1).val('No GPS Functionality');
        $('input:hidden[id^="answer"]', q1).val('No GPS Functionality');  
      }
    }
 
    function gpsError(error) {
      alert('GPS Error: '+error.code+', '+error.message);
    }
 
    function showGPS(position) {
      $('input.text', q1).val(position.coords.latitude+', '+position.coords.longitude);
      $('input:hidden[id^="answer"]', q1).val(position.coords.latitude+';'+position.coords.longitude);
    }
 
    getGPS();
 
  });
</script>

Code:
<script type="text/javascript" charset="utf-8">
 
  $(document).on('ready pjax:scriptcomplete',function(){
 
    // Identify this question
    var q1ID = '{QID}';
    var q1 = $('#question'+q1ID);
 
    // Click event for the button
    $('.gpsLink').click(function(){
      getGPS();
    });
 
    function getGPS() {
      if (navigator.geolocation) {  
        navigator.geolocation.getCurrentPosition(showGPS, gpsError);
      } else {  
        $('input.text', q1).val('No GPS Functionality');
        $('input:hidden[id^="answer"]', q1).val('No GPS Functionality');   
      }
    }
 
    function gpsError(error) {
      alert('GPS Error: '+error.code+', '+error.message);
    }
 
    function showGPS(position) {
      $('input.text', q1).val(position.coords.latitude+', '+position.coords.longitude);
      $('input:hidden[id^="answer"]', q1).val(position.coords.latitude+';'+position.coords.longitude);
    }
 
  });
</script>

GPS coordinates are not even showing in survey itself by using the script provided by you

Do I need more workaround?
