    Two Body running fix
    From: Martin Kühnl
    Date: 2019 Oct 28, 15:57 -0700

    Dear community members, i have been trying to program a casio application to solve the two body running fix for some time, going along with the approach of kenneth gibson who published a method in the Journal of Navigation in 1994. I have been trying to implement his formulas but either i make serial mistakes or the formulas are not correct. Can anybody give me some feedback or tell me if the algorithms mentioned in this article are correct? i found some other approaches to approximate the running fix not rigoroously in an article by Geri who mentions a´hearn and others who published in the journal of the institute of navigation. does anybody know the algorithms mentioned in those texts?  thank you very much in advance, martin
