every 10 seconds, the site will update the longitude and latitude.

I want to develop a navigation app and use my php website to retrieve the longitude and latitude information. I use Google Navigation to receive directions from my position to the location we get from the web. I want the programme to automatically update Google Navigation with the latest data every 10 seconds. How to automatically update the data is my issue. Can somebody assist me?

Use a Clock that alwaysFires and has an interval of 10000ms
