 Posted: Thu Oct 20, 2011 10:57 am Post subject: Galileo IOV - Launch Delayed |
 |
|
News has just come in that today's scheduled launch of the first two Galileo IOV (In-Orbit Validation) vehicles has been delayed.
The launch was to take place at 10:34 GMT today and everything had appeared to be been going to plan. The Soyuz ST-B launch vehicle moved to the pad in French Guyana on 14th October with the launch fairing containing the two Galileo IOV's placed on top later the same day.
The Soyuz passed a Launcher Readiness Review on 18th October and fuelling went ahead as planned earlier this morning. However, the launch countdown has now been stopped with ESA giving no further information other than "a new launch date will be announced later today".
We'll be following developments closely and will keep you posted as more information is made available.

Probably put diesel in by accident?

Launch is back on for this morning and fuelling is under way once again.
Launch is scheduled for 10:30:26 GMT (11:30:26 BST)

It would probably run on Diesel as its not that different to the Kerosene it should have in it - Mike |

Oh, well it wasn't that funny to start with.

The two iOV satellites are now in-orbit. After a lengthy trip that took 3hrs 50mins, the two Galileo iOV satellites were placed into their correct orbits 23,000kms above Earth.
They will form part of the 'In Orbit Validation' test which will allow the European Space Agency (ESA) to test the systems and the ground stations. With more accurate atomic clocks, Galileo will offer enhanced levels of precision when the network goes on-line in 2015.

Advanced levels of precision of what? Is this GPS? If it is GPS will it be better than USA version?
Thanks |

Its a new GPS system that will be more accurate than the USA system but the existing GPS receivers built in to navigation devices won't be able to pick up these signals, it will require new hardware - Mike |

We've already seen proof of concept chipsets with support for US, EU and Russian GPS networks so we will see support rolled out when Galileo comes on-line.
Apple's latest iPhone, the 4S supports US GPS and Russia's GLONASS and the more GPs networks a device supports, the better for the end user.

Thank you. Any idea how much more accurate the system will be compared to USA system? |

Pretty academic for a car nav system. Everything you need to know here |

You're not a Russian spy, are you, rukovich?

They reckon around 1 meter accuracy.
The most important thing is that Galileo will be a civilian system run by the EU (and a number of other countries) whereas the American Navstar GPS system is run by the American military and could be selectively disrupted or degraded if the Americans chose to do so.
GPS is now far too important to rely on an American or Russian system so we are building our own, much to the annoyance of the Americans...
