I am not sure, about the exact physical environment but if wifi access points are available then you can use sdk available from skyhook wireless or navision to locate your current position in case the accuracy of the gps position is not good.

This is not a failsafe approach, but may work better in areas where data is available about wireless ap.

In the general case, you can't get an accurate location indoors using Core Location. (What's wrong with your question is in assuming that you can, before asking how to do the impossible.)

You might get lucky if you are under to a tent roof that is paper thin or near a large window below lots of wide open sky, or happen to be between 3 or more nearby wifi access points whose locations are all accurately and precisely registered with whichever wifi database(s) Apple is using.
