In the RC Model Airplane world where some brave souls are experimenting with 
autonoumous (UAV)  flight , it is usual that they have a part-15 video downlink 
and/or telemetry at 900mhz or 2.4ghz and unless you put a trap on the input to 
the GPS receiver to significantly reduce those frequencies it can be expected 
that receiver de-sensing will occur and it is likely you will loose a very 
expensive 'toy'  A shorted stub is often all that is needed, but it is often 
required...
