Thank you for this advisory.
Can you please tell me how far inside the proclaimed jamming area the
pilots, who lost GPS signals, were flying?
The published radius from China Lake is approx 180 NM at 15,000ft - a huge
area if thinking of the Whites etc.
Is it possible that the area is the maximum likely and the real jamming area
might be somewhat smaller (and affected by terrain)?

I have been told that GPS Interference Testing is taking place. Several
folks are reporting a drop in signal which they then lose final glide
information. Several of our pilots had seriously intermittant GPS
signals on Monday, May 16. Here is an explanation:

Usually the tests are from 8pm-4am on most days for us here in NM.
They might only affect us on final glide on a good, long day.

From May 16-21, they are from 4pm-2am....this explains the trouble
pilots had yesterday.

From 22 June to 02 July, they will take place from 3pm-1am.

So, goe to the above site and check for your area, its possible your
area will be affected even if its not listed. Thermal tight, Soar high,
fly safe. # 711 reporting
