Can you use any handheld GPS system without operational satellites?

Handheld GPS receivers are nice. But what if the satelites are not functioning? Are they just paperweights then? Can I put myself at a place on the map where I am certain of the exact spot, and then use that information to navigate via the onboard maps and compass?
