VOXL Inspect GPS

This tool subscribes to the /run/mpa/vvpx4_gps_raw_int pipe published by voxl-vision-px4 which provides a copy of all GPS_RAW_INT mavlink messages received from a PX4 flight controller.

Also note that voxl-portal subscribes to the same pipe and also shows GPS satellites in the top right corner of the webpage.

Use

yocto:/$ voxl-inspect-gps

Troubleshooting

If no data is displayed, then either voxl-vision-px4 is not running or PX4 is not connected or operating. PX4 may also not be connected to a GPS or configured to enable it.
