60 CSx - WAAS Enabled ?

[outdoors4me]

Well I've read some threads on this and still don't really understand it. Is WAAS more accurate? Should it always be enabled?

 

Are there any downsides to enabling it?

 

Thanks, Beck

Yes, it is more accurate as long as you ar ein the coverage zone (most of the US and Canada), no there are no downsides.

WAAS makes the the GPS readings more accurate when the reciever can see a WAAS sat. It also increase battery consumption. I always leave it tured on. Anything that makes the signal more accurate is ok. I don't allways get a WAAS correction, can't always see a WAAS sat, but the 60csx tells you with a D in the Sat bars on the sat screen.

Thanks Guys,

 

I enabled WAAS and now I'm seeing D's in almost all the satellite bars.

 

Good stuff! I'll try it out tomorrow.

Here is a link to a Garmin website that explains WAAS (Wide Area Augmentation System) http://www8.garmin.com/aboutGPS/waas.html. Basically it is a system of satellites and ground stations that GPS signal correction. WAAS correction signals come from the "land-based" ground stations.

Hope this helps.

Land based stations gather data on delays, send their info to master stations, master stations analyze and produce a modeled grid of corrections, sends that info to the WAAS sats, WAAS sat sends that info to your gPS, your GPS selects what corrections to use based on where you are, and corrects the signals of the GPS sats.

 

DGPS is a land based signal.

WAAS corrections will carry for a while if you loose the signal. It's different then the other data the gps needs to update every 2 secs.

So I leave it on all the time..
