Cordova Geolocation code:

.controller('StoreCtrl', function($scope, $state, $cordovaGeolocation) {
    //Searching from map
    var Map;
    var Infowindow;
    var Latitude = undefined;
    var Longitude = undefined;

    // Get geo coordinates
    function getPlacesLocation() {
        navigator.geolocation.getCurrentPosition(onPlacesSuccess, onPlacesError, { enableHighAccuracy: true });
        //console.log("navigator.geolocation works well");
    }
    // Success callback for get geo coordinates
    var onPlacesSuccess = function(position) {
            Latitude = position.coords.latitude;
            Longitude = position.coords.longitude;
            getPlaces(Latitude, Longitude);
        }
        // Get places by using coordinates
    function getPlaces(latitude, longitude) {
        var latLong = new google.maps.LatLng(latitude, longitude);
        var mapOptions = {
            center: new google.maps.LatLng(latitude, longitude),
            zoom: 15,
            mapTypeId: google.maps.MapTypeId.ROADMAP
        };

        Map = new google.maps.Map(document.getElementById("places"), mapOptions);
        Infowindow = new google.maps.InfoWindow();
        var service = new google.maps.places.PlacesService(Map);
        service.nearbySearch({

            location: latLong,
            radius: 500,
            type: ['store']
        }, foundStoresCallback);

    }

    // Success callback for watching your changing position
    var onPlacesWatchSuccess = function(position) {
        var updatedLatitude = position.coords.latitude;
        var updatedLongitude = position.coords.longitude;

        if (updatedLatitude != Latitude && updatedLongitude != Longitude) {
            Latitude = updatedLatitude;
            Longitude = updatedLongitude;
            getPlaces(updatedLatitude, updatedLongitude);
        }
    }

    // Success callback for locating stores in the area
    function foundStoresCallback(results, status) {
        if (status === google.maps.places.PlacesServiceStatus.OK) {
            for (var i = 0; i < results.length; i++) {
                createMarker(results[i]);
            }
        }
    }

    // Place a pin for each store on the map
    function createMarker(place) {
        var placeLoc = place.geometry.location;
        var marker = new google.maps.Marker({
            map: Map,
            position: place.geometry.location
        });

        google.maps.event.addListener(marker, 'click', function() {
            Infowindow.setContent(place.name);
            Infowindow.open(Map, this);
        });
    }

    // Error callback
    function onPlacesError(error) {
        console.log('code: ' + error.code + '\n' +
            'message: ' + error.message + '\n');
    }

    // Watch your changing position
    function watchPlacesPosition() {
        return navigator.geolocation.watchPosition(onPlacesWatchSuccess, onPlacesError, { enableHighAccuracy: true });
    }
})

View Side(ionic):

<ion-view view-title="Store">
<ion-content ng-controller="StoreCtrl" class="padding">
    <div id="places"></div>
