www.gpsworld.com informs that PRN135 is now back to full healthy,
available for aviation and other safety of life applications.
But there's no word to that end on http://www.nstb.tc.faa.gov/ as well
as http://www.faa.gov/about/office_org/...nss/waas/news/
yet.
At the same time WAAS nstb SV status page shows PRN135 UDRE now at 50
meters. At this point PRN135 begins to really useful as a ranging
source for non precision approaches. This suggests that PRN135 has MT0
really removed. And this should mean absent any signal quality issues
in less than a day or two ranging UDRE improves to 7.5 meters (the
best possible for WAAS GEOs). UDRE 7.5 meters is useful for precision
approaches.
