[gps-talkusers] Re: WAAS IN UK

Hello Richard and list,
Sorry about the "WAAS" confusion, Mike experienced some of this too while in Australia and New Zealand last week, and we are still trying to figure out where the differentially corrected signals were originating from.
When the GPS receiver returns that the receiver Mode or "Quality of GPS fix" is a "2" it means the fix has been "corrected" by some means. In the USA / Canada it means "WAAS" in Europe it means "EGNOS" but currently we just say "WAAS" for anything corrected. We will be changing this in the future to have a more generic term instead of "WAAS" since we have no idea "how" the receiver got its differential correction. All we know is that if we get a quality of 1 it means no corrections, and 2=corrected.
So what do you all think about a new term that means we are receiving corrected GPS data that should be slightly more accurate? Any idea's? Instead of saying "WAAS" what should we say? 
"Enhanced", "Corrected", "DGPS"??

Thanks
Charles.

Hi,
I had an interesting experience this afternoon in that, for the first time ever in the UK, I received the message 'WAAS, 11 satellites' or words to that effect!
Firstly, I didn't think WAAS was available in Europe and, secondly, didn't realise that its equivalent (is it EGNOS?) was enabled.
Did I receive the WAAS message because it had detected EGNOS? If so, would there be much work involved in changing the message to reflect the system being used? If not, any explanation as to why I received the message?
The only other time I've seen this message was last week when I was in San Francisco; could this be related, eg the software retained some form of history?
Finally, I don't have a Holux receiver bought from Sendero so don't have the firmware changed to permanently enable WAAS; therefore, can someone remind me, please, what difference this makes? 

So, here's looking forward to even more accurate reception!
