I have been doing R&D work with various GNSS receivers using WAAS corrections from best available WAAS SV signal, which in my location has usually been WAAS PRN135. Was recording 24-hour data set on May 25/26 (GPS week 1637) and noticed that WAAS PRN135 dropped out and apparently quit broadcasting on or about weeksecond 38771. The test receiver equipment shifted over to get signal from WAAS PRN138 as it was designed to do. That was good, but in my reports to my client I have to explain this situation. Does anyone know where I can obtain official information on this WAAS event?
PRN138 seems to be the new signal source to replace PRN135 but it's sky location being well eastward (very close to WAAS133) may cause availability problems with West Coast USA users.
Any help would be appreciated.

It is 2011...
BC, We rec'd two Support messages from around the planet last few days; small hicup with DGPS SBAS sensors with same issue. The HGPS gear hick-up'd, burped and now working OK fine again. Simple reboot of receivers, no FW updates req'd.
Left U a message the other night. Claudio and Capt Dan where in Scottsdale for a couple of days this past week. Called U from bar. Claudio in LA for weekend, then back down to Santiago, Chile. DC back to San Jose Friday Night. Gotta answer your mobile dude... U call screener U

Thanks for the info guys. That solves the mystery. I vaguely recall the 2010 information on SV135. Haven't been doing many WAAS experiments lately, should have been keeping up on events.
Hey Bad Bob, sorry I missed your message. Up here in the backwater boonies I get no cellular signal at the house, so I only use my mobile phone when I go on the road. Try the landline. Glad you had a good time with El Jefe and The Capi-tan.

So, this was a receiver-specific problem? Which receiver?
No, not receiver specific. In fact the equipment in use handled the situation perfectly. It was a problem with WAAS SV135.
BC,
Sorry we missed making contact when Senior Claudio and Capt. Dan where in town.
Now I know better, to make contact on your landline. In my situation, I drag around x2 Smart phones. My personal mobile is an Android2; the work mobile is an iPhone4.
Customers often ask where I live, I tell 'em I have a mortgage in CT, I get to visit some weekends...
