Navigation Game Wishlist

For a long time I’ve wished there was a nautical game or sim that had accurate celestial navigation in it. And I was just thinking: I know how to make that work. At least in theory. So I wonder if there are any developers out there who would be willing to either add it to an existing game or – better yet – make a simple [or even complex] navigation simulator.

I have all of the formulas and algorithms ready to go in my spreadsheet (available here). It would just be a matter of tweaking them to work in whatever language the developer uses. And I could certainly provide some guidance should any problems arise. I even have a little bit of experience programming (I know: a little knowledge … ).

I don’t think it would be a trivial undertaking and I am in no position to finance the operation, so I’d understand if there were no takers. But if there were, I’d love to see:

A semi-accurate representation of Earth. Land masses could be complete abstractions, but positions and scaling would ideally be accurate.

A choice of at least one simple motor vessel and/or sailing vessel.

A simple [procedural] weather/current model. (If an accurate current model could be implemented, that would be awesome.)

Accurate celestial and navigational models (of course).

Some way during or after the voyage to compare one’s fixes with the actual ship’s positions to assess one’s performance.

A radar model and other ship traffic would be super cool, but not necessary.
