Sadly despite much pressure on SES we havent been able to persuade them to carry tomorrow nights Astra 1N launch on 28E.
If anyone without multisat capability wants to watch have a look here - http://www.videocorner.tv/index.htm coverage should start about 2230 BST for a 2253 lift off. (Assuming no more delays) If you are semi interested its worth watching at least the launch and first few minutes of the climbout - the Ariane 5's look fabulous as they take off ![]() ![]() EDIT - they will try again tomorrow. |

Perhaps it's Karma for not covering it on 28E

Since these threads recently seem to have turned into ones summarising the TV you can get on holiday:
I was in Croatia on the island of Lopud near Dubrovnik, and with my indoor aerial, I could receive... absolutely nothing, analogue UHF/VHF, or DVB-T UHF. The guesthouse had no TV system for me to check. I am now in Mostar in Bosnia & Herzegovina. The hotel (Villa Fortuna) has a good TV system with quite a few English channels (CNN, lots of Discovery channels, Nat Geo, and Cartoon Network IIRC), but my brother is currently watching Nat Geo so I won't yank the aerial out and check all the channels with my laptop. Instead, I'll list the (surprisingly many) channels I could receive at a watchable quality with my indoor aerial at the window: R12 - BHT 1 E7 - FTV E12 - BHT 1 21 - OBN 23 - FTV 26 - BHT 1 28 - mreza RTM 30 - mreza RTM 51 - mreza HTV 57 - Pink BH 60 - HTV Mostar I notice a lot of duplication, and channels being simulcasted on UHF and VHF, all in PAL colour. I was using the europe-east profile in mplayer, I assume that's the correct one to use here - if not, post before tomorrow and I'll do more scans with a different one. BHT 1 is the national public network, FTV seems to be the big regional public one, OBN, the mreza channels and Pink BH are the big commercial ones (though I don't know which are national and which are regional), and HTV Mostar was the very, very local one that isn't even really broadcasting at the moment (just showing pictures and music and contact details). No DTT whatsoever, despite very good analogue pictures - a bit of browsing tells me there won't be any until at least Spring 2012. |

If theres any delay they always hold at T-7 mins. Should there be a hold at less than T-7 mins they have to reset to 7.00 as this is when what they call the "synchronised sequence" starts This is basically the ground equipment starts to hand over control to the rocket computers

There is a "launch window" in which both the satellites can be placed into the correct orbits. Tonights is a long one - over an hour so we have plenty of time for the weather to clear yet.

Theres a good explanation of the synchronised sequence in the launch kit: Quote:
Appendix 3. The synchronized sequence The synchronized sequence starts 7 mn before ignition (T-0), it is primarily designed to perform the final operations on the launcher prior to launch, along with the ultimate checks needed following switchover to flight configuration. As its name indicates, it is fully automatic, and is performed concurrently by the onboard computer and by two redundant computers at the ELA 3 launch complex until T-4 seconds. The computers command the final electrical operations (startup of the flight program, servocontrols, switching from ground power supply to onboard batteries, etc.) and associated checks. They also place the propellant and fluid systems in flight configuration and perform associated checks. In addition, they handle the final ground system configurations, namely: • Startup of water injection in the flame trenches and jet guide (T-30 sec). • Hydrogen aspiration for chilldown of the Vulcain engine in the jet guide (T-18 sec). • Burnoff of hydrogen used for chilldown (T-5.5 sec). At T-4 seconds, the onboard computer takes over control of final engine startup and lift-off operations: • It starts the ignition sequence for the Vulcain main stage engine (T-0). • It checks engine operation (from T+4.5 to T+7.3 sec). • It commands ignition of the solid boosters for immediate lift-off at T+7.3 seconds. Any shutdown of the synchronized sequence after T-7 mn automatically places the launcher back in its T-7 min configuration. http://www.arianespace.com/images/la...c-JCSAT-EN.pdf |

Incidently as they have 2 big birds on board Arianespace are using the ECA configuration of the rocket and a long fairing. The ECA is the heavylift workhorse and can be identified as it has the yellow arms connected to the rocket that pull away 5 seconds before launch. The lighter stuff (eg the transfer vehicles that go the the Space Station) use the ES configuration and dont need the tanks topping up until the last seconds
