Is there not a modern equivalent of the medieval 'sun stone'?

- sethrin 11y agoKnowing the direction of the sun to within a few degrees is unlikely to help much. For one thing, you have no other "fix", and for another, an error factor of a few degrees probably represents an error of a few hundred (nautical) miles. You should probably read a bit more about celestial navigation to understand the problem.
