    Navigation without dead reckoning
    From: Sara and Dan
    Date: 2007 Dec 23, 08:57 -0500

    I am new to this navlist and any help would be appreciated.
    I occasionally travel to diffrent parts of the country and I think that
    it would be a fun challange to try to find the
    coordinates of the locations that I travel  to using celestial navigation.
    My problem is that since I am not traveling in a straight line at a
    constant speed it is not possable to calculate a
    dead reckoning point.
    I have no trouble with lack of horizon since I have a bubble sextant, a
    ball recording sextant and an artificial horizon.
    My thought is that there ought to be a way to get accurate enough
    coorinates by taking several noon sightings of the sun, graphing them
    and picking the highest point and using this time as local apparent noon
    to get longitude and using
    the observed altitude to get latitude.  If  I take these coordinates and
    use them as my dead reckoning position for later
    readings I think that this would yeald fairly accurate results.
    Is this  correct?  Can anyone suggest a step by step approach to doing
    this or any other suggestions about how
    I can use a sextant for land navigation without cheating by uaing a map
    or gps for coordinates.
