Hi, I have tried googling and all but im not even sure how exactly to call this. Basicly i am trying to search for a formula with wich i can calculate the diffrence in separation distance between 2 objects every orbit cycle. This will be usefull for me when making synch communication satellite orbits using the least amout of time and fuel. My guess this formula will include Ap-Pe of both objects and time for one orbit. Maybe someone already has such formula? As for now i will continue searching...
