It is mean what you receive SBAS ............
HaHA! Very funny g-man. I would think that you freezing northerners should APPRECIATE a view of the great Australian Bush, even on a rainy overcast day. If the sun was out here you'd need your Ray-Bans on just to glance at those photos. But yes, if i see PRN153 or PRN155, (btw, on the Russian forum weren't they talking about 225 not 155 on that guy's etrex?), or for that matter any other sat numbered above 32 again, i will just simply do a screenshot and save my doing any cropping, as there would not be any need to prove that the units were side-by-side contemporaneously in that case ......

All sarcasm aside, i'm pleased to see someone else using the term SBAS. Most ppl i talk to over here look at me strangely if i say that, then when i explain say 'Oh, you mean WAAS!' Now, back On Topic: Yes i know that it means the 3490 was receiving SBAS info, but my question was 'does that mean anything special' in regard to the accuracy problems. i.e. if the 3490 convert was receiving SBAS info but was showing a lesser accuracy than the original 3790 which wasn't getting SBAS, what's that mean when the sig strength reads about 60% for the SBAS sat 153? Shouldn't accuracy be better? Is this the reason some users have 15-20m readings, no SBAS info received?

Also, am i right in believing this?: There are only 32 true GPS sats, with PRNs from 1 to 32 inclusive, therefore any other number displayed by a GPS device is definitely an SBAS transceiver sat? And because it's showing an SBAS sat does that mean it can also use/process the SBAS info, i.e. that it is 'WAAS capable' ?

(Don't beat me up for asking these dumb questions, you're the one with GPS Software Expert after your nick).
