Seems like nobody wants to bite - I'll provide the answer over the weekend.

In the mean time, I've posted something over on the THE GREAT QUIZ CHAT that is of interest to this thread as well.

A great Q, Bishop! Not that I don't want to bite; just that the bait is too difficult to reach. :wink: Not quite sure where your Q is heading, so maybe an itsy-wintsy clue?

Thanks for the clue, Bishop! Sounds like something to do with sunspots and increased radio disturbances?? Will need to research this, though ... GREAT Q, B! :clap:

Too much carbon dioxide in the atmosphere could create hazards for low-orbiting satellites that power global positioning system?

Debris dropped at just the right height to ensure that it will fall back to Earth relatively quickly and burn up in the atmosphere. If the atmosphere contracts, there will be less atmosphere up there to get rid of all the junk?

Changes in the upper atmosphere could also affect radio signals being sent from GPS satellites?

Solar flares will disrupt GPS in 2011?

Navigation, power and communications systems that rely on GPS satellite navigation will be disrupted by violent solar activity in 2011, research shows.

A study reveals Global Positioning System receivers to be unexpectedly vulnerable to bursts of radio noise produced by solar flares, created by explosions in the Sun's atmosphere.

When solar activity peaks in 2011 and 2012, it could cause widespread disruption to aircraft navigation and emergency location systems that rely heavily on satellite navigation data.

Particularly intense solar activity occurs roughly every 11 years due to cyclic changes to the Sun's magnetic field - a peak period known as the solar maximum. :tongue:

Elzet! :thumbs_up:

The reason why it was not such a problem last time around is that we were not so dependent upon the GPS systems. Back in the '80s already we were driving around in the bush with SatNav systems on the vehicles, but they were big, bulky things, and only available to the military.

The version available to the civlian population is based on quite weak signals. So, the next time round when this solar flares with all their released energy is around... It may not affect the common man so much, because if you're 10 or 20 meters off so what. But, for ships that are autopiloting to docks, 10 meters can mean serious business! :big_eyes:

Quite in interesting and insightful article: Sat-nav devices face big errors as solar activity rises

Thanks Elzet & OWN. I'm on a couple of international mailing lists. On the one there's a number of librarians, and one from the UK and another from the US comes up with the most interesting links at times. Some of the weirdest stuff imaginable too! :big_eyes:
