R: Solutions to Gray's 100 Problems (Problem 1-1)
From: Federico Rossi
Date: 2007 Sep 27, 01:31 +0200

```Hi,
I've just found my notebook with the solutions to the problems.
I worked the sights with the classical haversine method and got the
following intercepts:
Kochab -1.9 Az 339
Rasalhague -14 Az 233
Alkaid -5.6 Az 311
Altair -4.1 Az 176
Venus +10.1 Az 97.5
Moon +4.4 Az 150
This gave me a fix at 40 13.5 N 49 58.5 W, which is practically identical to
the solution given by the book.
Hope this can help.
Federico

Oggetto: [NavList 3275] Solutions to Gray's 100 Problems (Problem 1-1)

Hi, I'm new to the list.

Speaking of the moon... I am working through Leonard Gray's book One
Hundred Problems in Celestial Navigation. I calculated and plotted all
the sights for the stars, the moon's lower limb, and Venus for the
first problem (1-1). My solutions for the stars and Venus seem OK, but
my line-of-position for the moon seems quite a ways off. I get a
pretty good solution without the moon (not more than one minute off of
the given answer, and that's using an 8.5 x 11 plotting sheet).
Is there anyone that has saved their solution to this in notes
somewhere? I would like to see if it is supposed to be so far off, or
if I left out one of the many corrections for the moon. The stars
using Pub 249 were sure much easier!

Secondly, does anyone know of any online celnav worksheet forms? I
website, but I thought I would find more on the internet than just a
couple forms.
