Answer 1

appControllers.controller('Ctrl', ['$scope','$routeParams', '$http','$window','$interval',
function geo_success(position) {
var lat = position.coords.latitude;
var lng = position.coords.longitude;
console.log(lat);
console.log(lng);
$scope.$apply(function(){
$scope.lat = lat;
$scope.lng = lng;
});
$scope.latlng = function(){
$http.post('/profile', {
latitude: $scope.lat,
longitude: $scope.lng
})
.success(function(user){
// No error: authentication OK
$rootScope.message = 'Lat/Lng send ok!';
})
.error(function(){
// Error: authentication failed
$rootScope.message = 'Lat/Lng dont send';
});
};
}
function geo_error(error){
console.log ("gps lost");
}
var watchID = $window.navigator.geolocation.watchPosition(geo_success,geo_error, {enableHighAccuracy: true });
}]);
this i have write

Hope this could help.
angular.module("GeoService",[]).
factory('GeoLocation',['$rootScope', '$window', '$q', '$resource', function($rootScope, $window, $q, $resource){
var _geoCapable = false,
_deferred = $q.defer(),
_errorMsg = null;
//Geolocation options
_option = {
enableHighAccuracy:true,
timeout: 5000,
maximumAge: 0,
desiredAccuracy: 0,
frequency: 1
};
if($window.navigator && $window.navigator.geolocation){
_geoCapable = true;
}
if(!_geoCapable){
$rootScope.$broadcast('geo:error', 'Geolocation not supported');
}
//Geolocation function onSucces
_onSucces = function (position) {
_deferred.resolve(position);
};
//Geolocation function onFail
_onFail = function (error) {
switch (error.code) {
case error.PERMISSION_DENIED:
_errorMsg = "User denied the request for Geolocation."
break;
case error.POSITION_UNAVAILABLE:
_errorMsg = "Location information is unavailable."
break;
case error.TIMEOUT:
_errorMsg = "The request to get user location timed out."
break;
case error.UNKNOWN_ERROR:
_errorMsg = "An unknown error occurred."
break;
};
$rootScope.$broadcast('geo:error', _errorMsg);
_deferred.reject(_errorMsg);
};
//Service API
var _locationService = {
//getPosition() function:
getLocation: function(){
if(!_geoCapable){
return _deferred.reject();
};
$window.navigator.geolocation.getCurrentPosition(_onSucces,_onFail,_option);
return _deferred.promise;
},
//watchPosition() function:
watchPosition: function(){

$rootScope.$broadcast('geo:error','Geolocation not supported');
};
$window.navigator.geolocation.watchPosition(function(position){
