Whats WAAS? What?

[Logan1475]

Just a question out of curiosity really, I noticed there are 'Normal', 'Off' and 'WAAS' options in the GPS mode settings. I have mine set to normal which seems to be working ok. Can anyone tell me what the WAAS option is for or does, or is it an American thing.

I know it obviously has something to do with satelite tracking (What with this being a Sat-nav device an all), but what exactly?

I understand it stands for 'Wide Area Augmentation System' and I think it may have soemthing to do with getting a more acurate signal. But if the normal setting, whatever that does, is working ok why do we need this other setting. 8O

you are correct, waas or here in europe , egnos , does allow you to get a more accurate location on your gps...waas cannot be received here in europe but egnos can...at the moment egnos is still in its testing stage although on numerous occasions i have caught the signal on a garmin 60c i used to have..for geocaching and the such its a great advantage as you can get right down to 6 feet accuracy but for motoring (30 foot accuracy) there is not much help .....one disadvantage of waas/egnos is that the gps has to work harder to get the extra satellite signal and this can sometimes slow the gps down...i would leave the setting to normal until egnos is up and fully running..

Thanx Zogman, My curiosity has been satisfied for now anyway till I find something else. I really must get out more.

Does that EGNOS come with CHIPNOS and BEANOS.
