Accurate enough for what???
Within a few miles - I would be prepared to bet on it, but if you are actually going to any proper nav/survey, you would want something with a bit more detail!
Almost every piece of (modern) GPS equipment I've used has a distance/radial function. Even models designed for ground based survey/navigation have this type of calculation included.
If you're really stuck, you could do some year 10 trig problems to deduce a Lat/Long for the required point!!!
