Celestial Navigation in 60 min
... We found a mathematical relation between what we know (delta, GHA, h) and what we are looking for (latitude, longitude). With 2 observations, we get a system of 2 equations with 2 unknowns that we are able to solve. The celestial navigation problem is thus resolved. What? You don't like my equation ...
