GPS Outages
Out of interest, has anybody suffered any odd GPS outages flying in England over the last few days.
I've had two, both in perfectly good conditions, both about 20 minutes. One was flying near Swindon early on Wednesday evening with a Garmin 55, and one was in my car on country roads in Hampshire on Thursday evening with a Garmin Nuvi.
No significant cloud cover either evening, and nothing NOTAMed that I could spot.

You need nano.aero - Report navigation anomalies and help make flying safer - they look after this kind of thing

I was told by another pilot of GPS outages being NOTAMmed last weekend, though I didn't have any problems and nothing appeared in my narrow route brief (Cardiff to Boston)

Interesting thread. I've been using GPS on the ground for 10+years on almost a daily basis and never experienced an "outage" and wasn't aware that such events occurred. GPS jamming does occur; it is NOTAMed and usually in a remote area well aware from busy cities, etc.
Cloud cover should not produce an "outage".

Several others, including myself, have remarked on "outages" in heavy cloud cover. Whether this is coincidence I have no idea.

A couple of years ago, flying from KFFZ in Arizona, my Bendix-King KLN89B starts acting up, map page all skewed, inop time/distance data, so I tell the tower.
They make a telephone call.
Yup, it's TRW again, with their test signals.
The FBI is called.
Their chief engineer on site is propmptly arrested and read his Miranda rights.
No problems since.
Nobody f***s with my GPS signal.
Period.
If they try, I know just whom to call.
A completely true story.
The FBI takes unwarranted GPS interferrance very seriously in the USA...jail time for the perps, make no mistake.

Who or what is TRW?
The TRW engineer-in-charge received six months in the local jail, next time, five years in the Federal pen.
The FBI means business with GPS attempted (or inadverent, in this case) interferrence.
