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.
