You can use arrow function like below:

if (navigator.geolocation) {
      navigator.geolocation.getCurrentPosition(p => {
        //var LatLng = new google.maps.LatLng(p.coords.latitude, p.coords.longitude);
        console.log(p.coords.latitude);
        console.log(p.coords.longitude);
        var dataObj = {
          latitude :p.coords.latitude,
          longitude:p.coords.longitude
        };
        this.http.post('https://XXXXX/datacenteres.php', {
          dataObj
        })
          .subscribe(
            res => {
              console.log(res);
            },
            err => {
              console.log("Error occured");
            }
          );
      })
    }
