I just finished reading this article from BBC News. I would never have imagined this was even possible. This will make you think twice next time its a dark rainy night and your looking for that harbor entrance. The GPS says its right in front of you?
Even more reason to brush up on those charting skills.

Scary indeed
Ray,
I had known that GPS satellite signals could be jammed by the military (name your country), but according to this article, jamming devices are cheap and easy to get.
Considering how dependent the modern world has become on GPS systems, and considering how obsessed with terrorism the West has grown, it makes you wonder why LORAN was killed off.
I'm not a super fan of LORAN, but it did work--and disabling it would require knocking out the networks of transmitters set up along various coastlines.
Guess I should learn how to use that sextant I bought back in 1967.

Joe You are right
Keep your old skills in shape
Here are a couple more things for your plate. Increasing solar activity to play with your GPS.

And then your satellite may not be there.

And tell me again why LORAN has been shut down, but I see the British are continuing with their eLORAN installation.
