The aluminum foil should be replaced with a good USB cable that has
the "bulges" indicating RF chokes. Adding additional RF chokes to
the cable on the end closest to the camera may help further. The GPS
cable should probably get an RF choke or two too. My final
suggestion is to hit the camera with an eight pound sledge and buy a
different one that has an FCC label. <br>

<div>Hello from the North!</div>
<div><br>
</div>
<div>I'm still working on the golf course robot. Recently I've
run into a rather odd issue. When I put everything together
for my 1/8 scale RC car platform, my GPS module refused to
converge. I spent a solid 4 days debugging it only to
eventually discover that the problem appeared to be that my
USB 3 camera was putting out large amounts of RF interference
of a spectrum suitable to interfere with my GPS even when
there was a metal ground plane between the GPS and the rest of
the equipment.</div>
<div><br>
</div>
<div>Eventually, a combination of wrapping the camera in metal
tape, placing the GPS with a ground plane elevated way above
the rest of the robot and wrapping the camera's cable in
aluminum foil finally got the GPS to converge. The only
problem is, the accuracy of the GPS is far worse than in the
previous version of the robot. Originally, I got within a 2-3
meters with an occasional drift. Now it squiggles all over
the place.</div>
<div><br>
</div>
<div>Does anyone know what I should try next to get decent
performance and/or hunt down any interference for the GPS?</div>
<div><br>
</div>
<div>Thanks,</div>
