What is going on ? Gran'ma carries a PDA which receives GPS data and sends it via GPRS, UMTS or WLAN to xmlBlaster (whatever is available). A tiny serlvet subscribes to those coordinates and your browser uses Ajax to refresh Gran'mas trip and displays it with Google-maps. Don't expect to see movements all the time, Gran'ma often takes a rest. Stay tuned and check again, sometimes she suddenly goes on excursion. |
