+SKUNK APE Posted May 1, 2006 Share Posted May 1, 2006 (edited) Is it advisable to always leave the WAAS setting on? Does this setting consume more battery power? Is it as effective on the ground vs. in the air? Edited May 2, 2006 by SKUNK APE Quote Link to comment
+Red90 Posted May 1, 2006 Share Posted May 1, 2006 It shouldn't affect battery life. I have not seen any real reason not to leave it on. However, being in Florida?? I doubt you can see any WAAS satellites at this time due to the reconfiguration currently underway. Quote Link to comment

Is it as effective on the ground vs. in the air? It is a choice, but you will have less position error when receiving waas. Others will disagree, but, yes, it consumes somewhat more power while searching for the waas sats and processing the data, but I've heard it is not a great deal of power. Somewhat more effective in the air because there are less obstructions. I leave it on except when in heavy timber. Quote Link to comment

Is it as effective on the ground vs. in the air? I advise leaving it on, unless you are sure you can't get WAAS reception wherever you are. Savings in battery life by turning it off is marginal at best. If you are planning a long hike in a forest, then not using WAAS is a reasonable choice, since your GPSr's accuracy will be suspect anyway due to the reduced number of locks to satellites. I still keep it on, just in case I run into a clearing. Quote Link to comment
+JSWilson64 Posted May 1, 2006 Share Posted May 1, 2006 For current area coverage, check here: http://www.nstb.tc.faa.gov/vpl.html I love that map. Typical government scientists (of which I am one) - nice pretty image, with no clue as to what it means! It's probably not intended for the average Joe, but a color-key would be nice. Blue is 20, dark red is 120. WTF does that mean to me? :-) Quote Link to comment

The Vertical Protection Level is half the length of a segment on the vertical axis (perpendicular to the horizontal plane of WGS-84 ellipsoid), with its center being at the true position, which describes the region that is assured to contain the indicated vertical position. It is based upon the error estimates provided by WAAS." It reflects assured accuracy of vertical position. The important thing is, it shows the current real time service area for waas with ionospheric corrections. The other link will show you service area without the ionospheric corrections.

+Red90 Posted May 2, 2006 Share Posted May 2, 2006 Except, 47 is the only Bird that is operational in view of the USA and it is not visible in Florida. http://www.lyngsat.com/tracker/inmar3f3.html 35 will work, but is not reading easily on the new "X" models.... http://www.lyngsat.com/tracker/inmar3f4.html Like I said, no fully operational WAAS birds are covering Florida at the moment.

+timk54 Posted May 2, 2006 Share Posted May 2, 2006 I own a Vista CX. Last Saturday I left it on with WAAS and Compass enabled and the rechargable batteries lasted for over ten hours. I think that is pretty good. Timk54 Quote Link to comment

It is not sending ranging, but the WAAS part of it is working. SOME of the new models with the new chip are having problems. Some are not. It is the units, not the birds that are messed. But you knew all that. I have offered current info on coverage. The coverage is there. Some of the new units may or may not work with waas even when ranging is restored. They need a garmin fix, which should be coming soon. Quote Link to comment
