Hi all , I have been doing a bit of math(s) on the images of the SES Astra fleet at 19 degs east. Assuming the FOV is 30 arc minutes , the "cube" within which the operators must keep their spacecraft is about 12 arc minutes on each side. An on slot distance of 140 km . Thats fine if you only have one bird to station keep , but SES have seven to manoeuvre ! http://mysite.freeserve.com/satcom_transits/box.gif ( 2 Mb ) shows just how good a job they do. Its a tribute to the expertise of SES's controllers that they have never violated their "airspace". Thats some precision flying !
