you don t have by any chance a formula that work on all direction ?

thank you for this I will try it when I get the chance today however this will apply a procedure in two times and ideally I'm looking for procedire on one-time procedure with the right direction and this formal I m sur it exist but I don't know how to get it might be an angle of x degree but I do not know how to Orient this degree in what direction. but thanks this is much better that what i had before your comment thanks again

allright but relative to what ? at lease you still need latitude longitude relative to the compass degree left or right degree up or down ?

hel lo is there a formula to get the vector direction or the angle with the orientation to apply thrust to match a different orbit and inclinaison : what does target button . thanks for any help
