Probably got lost following his saT nav …

“sat nav” uses old technology from the 1940s eg radio mast triangulation but with a “map” programme built into a phone or receiver.Thats why they do not work at sea or in aircraft.
Ships and aircraft use short wave signals for navigation but microwaves from cell phone masts only works on line of sight transmission.His parting shot was “well if I get done for speeding I will blame you”
If GPS satellites existed why do we need upward of 30,000 cell phone masts just to cover the UK.DUMBASS ALERT!!!
Satnav uses a string of satellites in geo-stationary orbit, not a string of masts on the ground. WASN’T THE NAME “SAT NAV” A BIG ENOUGH CLUE FOR YOU?. The satnav you have receives time stamp based signals from those satellites and works out where it is by the delay between the time of transmission and time of reception of the signal from each satellite. Ships and aircraft stopped using short wave for navigation when the GPS network went live for civilian use. Satnav works from any location on the planet with a clear view of the sky.
We need 30,000 cellphone masts because its an entirely different system where unlike GPS where the user is only receiving a signal, the user is also transmitting and not just receiving.
But thanks for confirming to everyone just how technologically ignorant you are. I hope you didn’t make a comment or smirk at him because it is actually YOU who is talking complete and utter ■■■■■■■■ and doesn’t know what they’re on about.
DUMBASS ALERT!!
GPS satellites are not in geostationary orbit. That’s what satellite TV uses (and is why the dishes always point towards the equator - to explain yet another of bking’s total muppetry pronouncements).
GPS works perfectly at sea and in aircraft (better than on dry land, because there are no mountains, valleys or buildings to block or reflect the signals). The reason it doesn’t appear to work on a ferry etc is because all that metal superstructure blocks the (very weak) radio signals from reaching inside the vessel.
Marine and aviation sat navs work better than your car or truck sat nav because they have to be constructed to more stringent regulations before they are passed for use, they can also one be a hell of a lot more expensive.
Yes, but even your consumer grade “satnav” works better out at sea or in the air than it does in the majority of places on terra firma, for the reasons I stated.
Evening folks
Our GPS satellite transmit signals at around 60w. That gets through clouds, smog and all the other nasties in our climate.
Cheers

Have subscribed to this thread, think its going to be entertaining

Think they are, the other option is geosynchronous (thank god for spell check) orbit which would only work over the equator and would be far to ■■■■■■ for GPS use.
It’s not rocket science 
[You know I’m googling this ■■■■ by now surely]
I’m trying to work out what the correct word should be, and more worryingly why your device has auto-corrected it to ■■■■■■!
Pretty sure geosynchronous and geostationary are the same thing - GPS satellites whizz round in several orbits, and rely on regular almanac updates to update their onboard positions. Sonflowerinwales can no doubt provide the exact details, and then carryfast and bking can come along and tell him his wrong he is

Not quite.

If you are ■■■■■■■ in harbour for a few days, does your GPS position vary at all, and if they have bizarrely included altitude in the display is it accurate enough to show you if the tide is in or out. and and and is ‘sea level’ when the tide is in or out or halfway, is it something to do with Liverpool.
I am sad enough to have already worked the following out, and my satnav can have my house moving by up to about 20m from side to side and about 20m up and down.

Not quite.

Good point - I didn’t think about inclined orbits. I knew they both meant the orbits would take a sidereal day (sadly, I can still remember the principle for working out a sidereal day!)
Still want to hear from DipperDave about the auto-correct though

It depends on how the filter is set, if the filter is set for say 1 second then yes it does fluctuate slightly but have the filter set to every five seconds then no. The filter is what decides the displayed position, basically averaging out the info received over a longer period of time depending on the vessels speed over the ground.(faster you go the less time in the filter, slower then more) One of our GPS does show altitude but I turned that facility off whereas the others don’t.

Ehhhh well this is slightly awkward but due to the varied variety of websites I visit on me phone and me phones learning dictionary I may have taught it to be a bit non PC.
This has nothing to do with the sister in lick ■■■■■■ reachround the other noshoff to burrow a teabaggin.
I knew you wouldn’t let us down
Gone quiet on here, thought bking would have replied by now?
Bking:

Nods head slowly
Because GPS satellites and cell phone masts are two entirely different things which operate two entirely different systems.
It’s a bit like saying “If fuel tanks exist, why do trucks need 60 fuses?”
