All the discussion regarding jamming GPS has been very interesting. Because
it is spread spectrum, I always assumed it would be difficult to jam GPS
For testing, I would suggest using a directional coupler in the antenna lead to
reduce the chances for unwanted radiation.

Hi,
for nonmilitary GNSS receiver, you do not need a wide band signal for jamming.
You only need a carrier with a signal power, sufficient to screw down the
AGC in the GNSS receiver's front end.
... and as a purpose for a military jamming exercise ... think of the
successfull detection of a jamme

All the discussion regarding jamming GPS has been very interesting. Because
it is spread spectrum, I always assumed it would be difficult to jam GPS.
The Monterey Bay incident indicates that it is extremely easy to jam GPS.
So, as soon as another project is out of the way, I intend to do some
