the Sun is awakening...not good news!

oh great...

basically to sum up..

..."If we project those forward, it varies quite a lot across the Earth; looking at the UK it will be about 10-metre errors in the positioning."

The errors would be much more long-lasting than the "blindness" problem, lasting hours or even days.

"Ten metres out is probably going to be OK for a sat-nav system in a car, but if you're using the system for something safety-critical like ships coming into harbour for navigation or possibly in the future landing aircraft, you're looking for much greater accuracy and more importantly, much greater reliability."

10 metre's out....I think I can cope with that!

I don't believe it's going to cause 'big errors'. It's going to reduce accuracy, which is a different and lesser issue altogether.

Forget the Satnavs. On another thread on these fora someone warns that this vigorous sun activity will increase cloud cover and thereby global warming.

I presume, as I write, Broon and Darling are sending me a tax demand for me to pay on behalf of the sun.

indeed not, approx 10 metres they say... more trouble could be had with trains by the sound of it that rely on gps positioning to allow doors to open when at stations, I guess if opening a few metres away from where they should do you will walk into one of those perspex walls!! What fun!

10 metres inaccuracy - thats an improvement!

A Europhile friend of mine (who is not a techie) derived great pleasure from telling my that Galileo, being immersuarbly superior, would not suffer from this issue. He was a tad nonpluissed when I questioned which Sun and planet system he was inhabiting
