You can turn on the gps using

LocationManager locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
LocationListener locationListener = new CTLocationListener();
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 1.0f, locationListener);

and turn it off using

locationManager.removeUpdates(locationListener);

Or you might also find this another thread on gps of use: How can I enable or disable the GPS programmatically on Android?

    try
                {
                dataMtd = ConnectivityManager.class.getDeclaredMethod("setMobileDataEnabled", boolean.class);
              } 
              catch (SecurityException e1) 
              {
                // TODO Auto-generated catch block
                e1.printStackTrace();
              } 
              catch (NoSuchMethodException e1) 
              {
                // TODO Auto-generated catch block
                e1.printStackTrace();
              }

                dataMtd.setAccessible(true); 
               try {

                dataMtd.invoke(conm,true);


                //gprDisable();
              } 
               catch (IllegalArgumentException e) 
               {
                // TODO Auto-generated catch block
                e.printStackTrace();
              } 
               catch (IllegalAccessException e) 
               {
                // TODO Auto-generated catch block
                e.printStackTrace();
              } 
               catch (InvocationTargetException e) 
               {
                // TODO Auto-generated catch block
                e.printStackTrace();
              }

and if you are making the options to false, you can disable the GPS. Hope this may help you.
