Galileo satellite in trouble

It appears that one of Galileo's in-orbit validation (IOV) satellites may be in trouble.

GSAT0104 has been flagged as 'unavailable until further notice' since 28 May (see here). GPSWorld is reporting that observers have been unable to detect any signal from the satellite since May 27.

The ESA have made no official announcement about the issue but speculation is mounting that the issue may be serious and linked to a component used for signal timing.

This is the first serious issue to affect Galileo's fleet of satellites but these are still validation vehicles and they exist to test the hardware and identify faults before the full constellation of satellites is launched.

Likely a dumb question, but will we all need to buy anew sat nav when it's all up and running or will older ones just continue to use the existing satellites only, I assume the latter.

Your old satnav should continue working OK using the USA GPS satellites - the Galileo system will be another system that duplicates them, but independent if required

And there are other systems that are also available as a lot of GPS systems are compatible.

Other satellite navigation systems in use or various states of development include:

GLONASS – Russia's global navigation system. Fully operational worldwide.

Galileo – a global system being developed by the European Union and other partner countries, planned to be operational by 2014 (and fully deployed by 2019)

Beidou – People's Republic of China's regional system, currently limited to Asia and the West Pacific

COMPASS – People's Republic of China's global system, planned to be operational by 2020

IRNSS – India's regional navigation system, planned to be operational by 2014, covering India and Northern Indian Ocean

QZSS – Japanese regional system covering Asia and Oceania

But possibly on different frequencies and encryption.

I think I read somewhere that the GPS receivers in the newer Nokia/Microsoft smart phones can use both the US and Russian satellite data.

How do you do that then, me being a none techy type.

You don't. They just do it.
If you load the 'GPS Status' app. GPS sats are indicated by a round blob and GLONAS by a square blob with much higher IDs (up in the sixties)
