Is there a way to allow an app to "wake up" the GPS?

Ok, let me set the stage here. I am trying to extend my battery charge time as much as possible so by default I have the GPS in 911 mode usually (turning it on when I need to). This is fine, and I have no complaints about turning it on and off at need.

My problem is that I have no short term memory (10 second Tom from 50 First Dates comes to mind), and I am constantly misplacing things. I have not misplaced my phone yet (fortunatly, I am also OCD about things to compensate for my short term memory issues, and keep my phone in my left pocket or shirt pocket if I have one). But the day will come when I misplace my phone. It has happened before (I usually call it over and over and over walking around trying to find it).

So, I found this program SmartPhone Tracker. Seems pretty cool. Installed it and it is pretty cool. One problem, I usually have my GPS off (to save the battery). So this program doesn't help at all if I loose it since it will most like happen when the GPS is off.

Now my question, is there a way (setting or application) to allow a specific application (say SmartPhone Tracker) to turn on the GPS radio if it is off so it can be used (in much the same way that the phone dials a internet connection if it needs one)? I understand if I have to manually turn it off (like said internet dial up connection), but having the ability to turn on the GPS seems like a good idea that I am sure someone has thought of before me.

Any ideas?

Thanks
