GPS GPS GPS!

What I don't get is this:

Isn't the AGPS chip using satellite data as well as tower triangulation and muxing all of that info together (with aid from the carrier's location server) to give you highly accurate positional data for things like Telenav and E911?

So if the chip is getting GPS satellite data for AGPS then why does a lack of an antenna preclude using it for standalone GPS? What is different about the standalone mode that requires an antenna?
