GPS top speed

There's something wrong with mine. I'll cop to 120ish, but no fucking
way did I do 178.

 

It's set to kilometres.

 

No, it isn't. Actual speed reads accurately. Top speed goes silly
sometimes.

 

The Tomtom on my pocket pc was indicating 530mph a couple of weeks ago, mind
you I was in an Embraer jet over London

 

So Garmin is shite?

 

Maybe Garmin have a problem. I'll contact them and see what they say.

I was thinking about this.

TomTom recorded perfectly a top speed of some 400km/h.

When landing inside a plane.

 

My Garmin has always given perfectly believable max speed readings.
It's an old GPS 3+ but does its job perfectly well.

Maybe, but my Vstrom is not capable of 178mph.

 

<wags finger in WUN stylee>

That's naughty, it's supposed to be turned off for landing.

 

Clearly. But it's presumably your specific unit, not Garmins in
general, that are at fault.

Acherly, it's much more likely you just went through some poor
reception areas - if the unit gets a reflected signal it may think
it's somewhere it isn't, and that it's got there, or gets back to the
real position, much faster than is possible. Almost certainly what's
hapenned here.

Now look here, stop putting fact and reasonable argument in the way of
a good rant, eh? This is UKRM not RSE, remember.

 

<curious>

Why? It's a receiver not a transmitter.

 

I'm glad I'm not the only one who does that.

 

'Cos the airlines insist that all electronic devices are turned off
for landing. Probably safe, but any such device will emit some
electromagnetic radiation, which theoretically could interfere with
controls. Safest, they reckon, to turn everything off rather than
worry about what is or is not safe.

Oh, right, so the patently utter bollocks "safety" reason. Fair enough

You can have 300+ video screens installed in a plane with no problem and 10
or more simultaneous audio feeds to the seats, but a passive receiver is a
no-no.

I suppose you have to have a blanket ban though, otherwise some dick would
doubtless bring a 100W transmitter on board and start fucking about with it
at 20,000 feet just to see if it works...

 

Perfectly normal.

Your GPS is using the distance between the two fixes it's found to be
furthest apart and the time interval between fixes to work out a speed,
then it compares and stores it if it's the largest.

In theory that gives top speed.

In practice it's measuring the biggest error it made made between two
fixes.

So if you've gone under some wet trees or something and it's got a fix
50m ahead of where you are a big speed is recorded.

 

Ah, sensible answer. I was in amongst the trees when it happened.

 

Right, I was in the redwoods when it happened.

You were doing 178MPH in the forest? You irresponsible ****, you could
have hurt a squirrel.

I'd have you shot.
