It depends on the GPS receiver. The GPS chipset won't know (it knows where it is and can remember where it was to know what direction it's moving), but some consumer GPS receivers (Garmin, Magellan) have electronic compasses built in. My Garmin eTrex Legend does NOT have a compass built in, but taking about 2 steps in any direction will tell me which way I'm moving. It can't do this when stationary. My buddy's eTrex can point north without moving, but that feature drains the battery faster.
The actual GPS receiver and the navigator is two different things. A GPS navigator may use additional sensors such as accelerometers and magnetic sensor to aid in addition to the GPS receiver built into them.
So a navigator may know, even if on a fixed location, but the GPS receiver does not have that information.
It is important to keep these separated so that they can be discussed properly. I don't want to say stuff like "The actual GPS receiver in the GPS receiver...".
