Hi all, Just tried to find out how the orbit will look. Very unscientific I just used FENGYUN 3A and modified the Mean Motion to 13.19 orbits per day. Then the height becomes approximately 1200 km. As far as I can find out, FENGYUN 3A was sent up from the same spaceport as XW-1 will be. I used NOVA for Windows. It allows the change without complaint :-) 73 OZ1MY Ib
