Re: [psas-avionics] GPS outage
A little background info for those interested: These are scheduled test events for verifying and validating the WAAS GPS position-enhancement system for air flight guidance. Here is the report issued in 2014 for the 2013 year: http://www.nstb.tc.faa.gov/reports/PAN84_0114.pdf You can see the test events discussed in Section 8 of the report, although I was not able to quickly find details on the nature of the testing. I am sure that data should be findable if interested. I am told by a friend that these tests are done quarterly, but I don't know the veracity of that information.

This is ridiculously perfect. I'm totally willing to go along, not sure I'm up for driving people though. But count me in, somehow!

I'm up for the drive with a couple passengers. I wonder if this will impact any of the higher altitude rockets acquiring GPS lock while at apogee this weekend at NXRS. This is why we need a cube-sat with SDR and directional antenna in orbit. Then we could pick up ground based interference from our bathrobes. -- Kenny -+---+++-++---+--+-+-++--++--+-+-++--+++-+++-++-+++---++--++ On Mon, 2015-06-22 at 11:28 -0700, Theo Hill wrote: As far as finding a spot to observe in Oregon, Mt.
