when I run:

raspivid -n -t 0 -rot 180 -w 960 -h 720 -fps 30 -b 6000000 -o - | gst-launch-1.0 -e -vvvv fdsrc ! h264parse ! rtph264pay pt=96 config-interval=5 ! udpsink host=192.168.1.67 port=5000

it comes up with a warning GPS Glitch.

The GStreamer overlay appears, but the GPS goes off line:

I get no GPS fix at all.

When I stop the streaming process on the RPI… the GPS come straight back on line.

I think I found the problem… seems there is significant interference from camera (Raspicam 1.3) cable with the GPS antenna cable. When all cables were physically separated as far as possible the issue goes away.
