Please note the email from Forest Mitchell ( WFO) and advice me of
anyone you know or that may be conducting experiments that would
interfere with the GPS signal ?
Thanks,

In the past week, we have been experiencing interference with acquiring
a GPS signal for the radiosondes we launch for Upper Air flights. The
GPS signal is critical towards acquiring accurate wind data aloft.
The interference is centered around the NWC, as measured by coworkers
using a variety of GPS devices. The interference occurs during the
afternoons, affecting us
during our launch window from 5-6:30 pm. It then disappears around 7
pm. There is no interference during the morning flights.
Is there some experiment being performed by someone within the NWS
community that could be causing the interference? We would appreciate
your efforts to find the source
so that we may create a solution to allow us to perform our mission in
its entirety. Thank you.
