background-process

I want to create an (game based) iPhone application which sends your GPS location on a specific time (like 3-5 times a day) to a server. I found an apple page explaining some functionality to run in the background like location, music and VOIP. I need the GPS to be accurate on the meter. Can someone help me with a small example?

Is the HKObserverQuery the only way to get data in the background
