What launch vehicle, spacecraft and target orbit parameters decide the time of launch to GTO for satellites destined for GEO?
The target orbital slot is always in the same relative position to the launch site so it seems like the launch should be possible anytime?
Some example launches and their windows (all from the Cape):
- SpaceX - SES-9 - 23:35 to 01:06 UTC
- SpaceX - JCSAT-14 - 05:21 to 07:21 UTC
- ULA - MUOS-4 - 09:59 - 10:43 UTC
I know there has to be a window - range, people at work, exclusion zones for ships and aircraft - nothing of these can stay ready indefinitely.
