You might find some useful information by following the guidelines of cave surveyors. They already assume that the tools need to be portable, durable, and work without GPS access.

I know an expert urban explorer and while GPS fails underground,

the mind of the explored does not fail unless he/she falls.

But I think you are looking for an inertial navigator based on three mutually perpendicular accelerometers to fix your position in 3D space.

As a mere lad you hardly have the ability to appreciate the software needed to accomplish a dead reckoning navigator of this esoteric type in the presence of a G-field.

BTW , the military may sell you an old but large model.

Maybe an entomologist could help you train some insects to do this handy back-track caricaturization, Like crickets in an LCD match box :)

So basically a 3D digital map?

The ones I know, gave X,Y,Z numbers from a starting point and when 3hrs later you returned to the crawl in point, it was a half inch off the mark.

That 3D map is in your mind !

Just with three accelerometers, though I would use a set of three and a master uP voting two out of three.
