    Re: Near-pole CN? Transverse Mercator?
    From: Tony Oz

    Thanks for all the replies!

    I know the "Pole is AP" trick, but it works only in vicinity (~2° as the books say) of a pole.

    What do I do at, say 75° Lat? Or at 80°?

    I found this page and it is a good insight (on the topic of the Grid Navigation) but too much about gyrocompasses. I need similar (beginner's) material with more attention to sights and reductions.

    Warm regards,
    Tony
