I have also work for simillar app using sencha touch 2.3.1
Using Ext.util.Geolocation class for get current location and automatically update the currentPosition using the following code. 

Ext.create('Ext.util.Geolocation', {
autoUpdate: true,
allowHighAccuracy: true,
frequency: '5000', // set the milliseconds for the location update
listeners: {
locationupdate: function(geo) {
    latitude=Global.currentUserLocations.currentLat;
    longitude=Global.currentUserLocations.currentLong;
    if(Global.currentUserPositionMarker)
    {
        latlng1=new google.maps.LatLng(latitude, longitude);
        Global.currentUserPositionMarker.setPosition(latlng1);
    }
   }
 }
});

The above code worked for me and i have already used in my app for getting currentLocation and moved the marker into currentPosition.

It's a lot simpler if you just use Ext.Map.getGeo() as follows:

    var geo = extmap.down("#Map").getGeo();
    var currentPosition = new google.maps.LatLng(geo.getLatitude(), geo.getLongitude());

As long as you have your map instantiated, it should get the current location if the browser client allows for you to obtain that.

HTH!

Nice question. I faced a similar problem before. But, later, I figured out the solution.

Here's how you can solve it.

Demo with Phonegap's Geolocation API

  1. Get the geolocation via the geolocation api.

    vat lat, lng;
var geoLocationOptions = { maximumAge: 3000, timeout: 5000, enableHighAccuracy: true };
navigator.geolocation.getCurrentPosition(geoLocationSuccess,geoLocationError,geoLocationOptions);

function geoLocationSuccess(position) {
    lat = position.coords.latitude;
    lng = position.coords.longitude;
    Ext.Msg.alert("Geolocation","Latitude:"+ lat +", Longitude:"+ lng); 
}

function geoLocationError() {
   Ext.Msg.alert('Error','Error while getting geolocation');
}

  2. Then use the values of lat and lng to set the map's center to it as well as set the marker's position to that value.

     ... 
 ...
 var position = new google.maps.LatLng(lat,lng);
 map = this.add({
        xtype: 'map',
        getLocation: true,
        autoLoad: true,
        mapOptions: {
            zoom: 15,
            center: position,
            mapTypeId: google.maps.MapTypeId.ROADMAP,
            navigationControl: true,
            zoomControl: true,
            mapTypeControl: true,
            scrollwheel: true,
            scaleControl: true,
            zoomControlOptions: {
                style: google.maps.ZoomControlStyle.LARGE
            }
        }
    });

 marker = new google.maps.Marker({
        id: 'geoLocMarker',
        position: position,
        map: map.getMap(),
        visible: true
 });
 ...
 ...
