Euro GPS Satellite

#1
I see Europe has launched it's own version of the GPS system so we won't be reliant on the Yank system which is a good thing but;
it was launched from a Soviet rocket!what has happened to the French led European rocket system based in S.America?
I seem to remember it had a few problems but I've never heard of it for a while.
It was the French baby but I think we and a good few others poured money into it,is it still functioning?
I would Google it if I could remember the name.
Why didn't it blast the GPS system into orbit,not reliable enough?

BBC News - Europe's first Galileo satellites lift off
No explaination on why they used a Soyuz to put it up into orbit, but I suspect it has more reliability than the French rockets. The project is already way over budget and a decade behind its schedule. Meanwhile a German spacecraft V2 varient is due to re-enter the atmosphere on Sunday.At least now if the satnav lets me down I can honestly blame the French. (every cloud has its silver lining) :-D

Why is it a good thing ?
The GPS system is up there doing a grand job for free, syndicated to who-ever wants to use it such as TomTom, etc.
The EU have come along and decided that the United States of Europe can compete with the United States of America. So for no other good reason have decided to blast a load of satellites into space, to do a job that is already being done.

Who do you think will pay ? We will.
How will we pay ? Its the first step on the road to toll charges. All number plates will be fitted with a chip, and your driving details will be monitored and billed. That was published around a decade ago, in the small print.

Still think its a good idea ?

To be fair, the Galileo system will be much more precise than GPS (essential for many of the latest technical applications), free for the public user and have certain other benefits, especially for the continent of Europe:
Satellite technology is used for applications including in- car navigation, time-stamping transactions at banks and powering telecommunications. Unlike the Global Positioning System, developed by the U.S. military, Galileo is designed for civil purposes and aims to end Europe’s reliance on GPS. Galileo will also have a commercial, fee-based service for high-precision, guaranteed signals for use in areas including mining, surveying and mapping, which GPS doesn’t offer.

“Europe is now a step closer to having its own smart satellite navigation system, which will bring many benefits to our economies and our daily lives,” the commission said.

The system established may generate 90 billion euros in additional revenue and in public and social benefits over a period of 20 years, the commission said.

‘Guaranteed System’

Galileo also will provide “a guaranteed system that won’t be vulnerable to being shut off for political or military reasons,” Godkin said.
The calculated benefits and the direct and indirect revenues from Galileo are expected to be substantial, fully justifying Europe's commitment. Galileo is very much a commercial initiative aimed at capturing a significant share of the satellite navigation market. It is not a flag waving exercise. The commercial, technical and market benefits have been carefully studied and laid out in very detailed market studies. As a result, civil aviation will be a major beneficiary of Galileo, although aviation is still only a very small percentage (around 1%) of the satellite navigation market....

2. The General Benefits of Galileo

Galileo is a system that will benefit all modes of transport including road, rail, sea and air travel. Galileo will, in particular, result in real and direct benefits to civil aviation. The clearest of these is the fact that satellite navigation will become a fully redundant service for civil aviation users in the event of a satellite or system failure. The number of satellites in view will grow dramatically and become fully independent in the case of failure to either GPS or Galileo. Galileo will work with GPS to provide greatly improved satellite coverage and availability, ensuring that sufficient satellites are always in view to obtain an optimal navigation solution. This has been one of the major impediments of a GPS only system and one stumbling block to the potential wider benefits that satellite navigation could offer civil aviation, but which it has not so far been able to deliver.

Certified services will also be offered, with guaranteed service levels (in terms of accuracy, redundancy, integrity, reliability and availability) and a more robust signal in space. This will enable the global implementation of ICAO's CNS/ATM concept.

These benefits will bring satellite navigation forward as a realistic replacement for conventional navigation aids in civil aviation. Despite the fact that satellite navigation has been with us for some time and that airlines have made significant investments, there has been, so far, relatively little return in terms of improved navigation services to airlines. Galileo looks set to change this and accelerate the introduction and benefits of satellite navigation for civil aviation Users.

Galileo also complies with the need for civil aviation services to be free and unfettered, a fundamental requirement enshrined in the ICAO convention...

Thanks Mate,I never knew about the German V2 hope it doesn't land on London!
Relax - It missed London, SF:

<<...The Roentgen Satellite (Rosat) re-entered the Earth's atmosphere between 01:45 and 02:15 GMT.

Just as for Nasa's UARS satellite, which plunged into the atmosphere in September, there was high uncertainty about the final moments of Rosat.

But if the timings are correct, any wreckage would probably have dived into the Indian Ocean - although no eyewitness reports have yet come in.

If anything did manage to make landfall, the likely areas to be affected would have been Myanmar and China...>>

Turning towards the original track let's not forget HMS ROCKET: Eight of 'em, the last one a Type 15, sold for scrap in 1967.


...then there were those brave souls who were encouraged to slap in for the Polaris Rocket Pilots Course.:slow:

Wandering back on track, I watched a news item on this rocket launching. One of the reasons as to why the Soyuz rocket was used was due to its simple design and thus cheap to use.

So more eventual profit to "them" when you have to start paying a fortune to use it.

I wouldn't mind betting the Ruskies photgraphed every bit of the Euro GPS system before it fired off!if they didn't have it already.
Maybe a certain ****** of an MP didn't notice his lover photographing documents over his shoulder as he heaved and strained in love!!!
I think his job is toast come the next election unless he stands for the Raving Loony Party!

The Soyoz rocket is being used untill the Itallian launch system "Vega" comes in in a couple of years time(We too could have a launch systen and humungus National Dept to go with it if we like). Ariane is too big and nothing going in the right orbit to piggy back.

Its being launched in Guyana to prevent the Russians having access to the interesting bits.

I thought that Guyana was used due to its physical location? i.e. close to the equator so the rocket gets a bigger sling shot effect and thus can carry a bigger pay load.

I could be talking bollox of course and if so I'll just blame the TV news story :)

The near-equatorial launch location provides an advantage for launches to low-inclination (or geostationary) Earth orbits compared to launches from spaceports at higher latitude. For example, the eastward boost provided by the Earth's rotation is about 463 m/s (1,035 miles per hour) at the Guiana Space Centre versus about 406 m/s (908 miles per hour) at the United States east coast Cape Canaveral and Kennedy Space Center spaceports which are at 28°27′N latitude in Florida.[4]

So it has a 120 mph less speed to aquire to get in to orbit from Guiana

Sorry shippers, I read it as 1035 - 908 equating to 133 miles an hour faster at Guiana. Again, I could be wrong, I'm tired, v tired, waiting for the washing machine to finish so I can put the Strimmers bedding in the wash as he has just puked after having a coughing fit. Doctor' for you me laddo.
