Finding vectors for Gauss method

barbara_bi1988 Aug 6, 2012

Hi everyone,

I'm a new member of the Findorb group and I hope you can help me with some issues..

I'm writing my own c++ program for determining the orbit of a body with Gauss method and I have some problems in calculating the three vectors (at three times) earth-body (actually i need unit vector).
I found out that Find_orb uses Gauss method too and I was wondering if you have done a specific function that I can integrate in my program.

I also tried to download the c++ package but it seems to me that there is not such a function (maybe I didn't recognize it) and when I try to compile the Gauss.cpp program I have a great number of errors that could come from the lack of libraries. For example I think that the libraries

"watdefs.h"
"afuncs.h"

are actually missing.

I really hope you can help me with these problems...

Thank you!
Barbara
