Has anyone else noticed any issues with their WAAS
GPS installation?
I just convereted a 530 and 430 to 530W and
430W. My GPS antennas are on a tray just under the glass
section in front of the vertical stab on my IVP. Since I got Waas I get
"No GPS navigation - user other nav" message. It happens on the ground, it
happens whether near buildings or not, it happens to both navs but at different
times. It lasts from 30-45 seconds typically.
One theory that has been put forth is that the WAAS
units look further down the horizon (or need to to get a big enough
constellation) and that I may have some blockage at those low
angles. So far I haven't seen this happen in the air.
I also converted my cessna 530 to
530W. I haven't noticed any issues. The antenna is
OUTDOORS in that installation.
