|Coordinates conversion to bearing and distance|
Message #1 Posted by rodf on 23 July 2007, 12:43 a.m.
I stumbled onto this forum while looking for an old calculation I used to perform with my HP11C back in my civil draughting days.
The quick calculation involved converting latitude and longitude coordinates into a bearing and a distance using only the functions on the 11C : hr/hms, sigma +/-, polar/vector.
The old 11C finally broke down and I now have a 32sII (- once an rpn user, always an rpn user -) but for the life of me I can't remember how to perform the conversion and was wondering if there was a forum member here that may know the correct way to do it??
I'm an avid fisherman and I'm keen to find the answer so I can use it for quick navigation purposes. Any help is greatly appreciated.
Apologies if this has already been discussed and answered.

I think the formula is in the 11C manual. I don't have the manual now but I remember that there is such a formula in the book. It would be easy to adapt it to the 32SII.
