Example of Angular service using ngCordova GeoLocation

app.js

(function() {

var app = angular.module('app', ['ionic', 'ngCordova']);

app.factory('GeoService', function($ionicPlatform, $cordovaGeolocation) {

  var positionOptions = {timeout: 10000, enableHighAccuracy: true};

  return {
    getPosition: function() {
      return $ionicPlatform.ready()
        .then(function() {
          return $cordovaGeolocation.getCurrentPosition(positionOptions);
        })
    }
  };

});

app.controller('LocationCtrl', function($scope, GeoService) {

  function showMap(coords) {
    var mapOptions = {
      center: { lat: coords.latitude, lng: coords.longitude},
      zoom: 8
    };
    var map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
  }

  GeoService.getPosition()
    .then(function(position) {
      $scope.coords = position.coords;
      showMap(position.coords);
    }, function(err) {
      console.log('getCurrentPosition error: ' + angular.toJson(err));
    });

});

app.run(function($ionicPlatform) {
  $ionicPlatform.ready(function() {
    if (window.cordova && window.cordova.plugins.Keyboard) {
      cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
    }
    if (window.StatusBar) {
      StatusBar.styleDefault();
    }
  });
});

}());

Thank you, I tested something similar but didn't work so I added a setTimeout with 10 milliseconds for delay and that worked.
I will try this again
