Landmark Based Outdoor Robot Localization

If anyone could shoot me some ideas that would be great.

There doesn't seem to be enough information about the problem yet in your description.

Answers could currently vary from dropping a track as you follow (and "learn") the path, to setting up transponders for triangulation, to using inertial navigation devices, to putting encoders on a wheeled vehicle, to ...

You also didn't specify the accuracy, precision, or repeatability you need; and/or whether you always start from a known location.

You also implied that you care about cost, but didn't do more than that.

The project sounds like fun, but with the info you supplied so far, your "solution space" is mighty big. Potential helpers will have a hard time offering practical advice without more info.

It's Is this a homework project, or a just-for-fun, on-your-own project?
