I am trying to build a remotely operated vessel that will include a GPS. I have been following advice on these posts:
Some of them use the recommended GPS by the Ardupilot website. However I was not able to purchase any of them, due to lack of stock or because they were discontinued. I got this one from RadioLink, but I do not know which value should I assign to the GPS_TYPE variable. I tried the uBlox option (variable value = 2) and it seems to be working (it shows the position in Qgroundcontrol) but I do not know if this is the best option. Is there any difference between these variables other than the name or a more detailed description of them ?
Also I would like to use the GPS data to position the vessel. I have read the GPS positioning section of Ardusub and I am a bit lost here, because I do not know how to forward the NMEA data from my GPS connected to the Pixhawk to the companion computer.
I also have a BU-353S4 USB GPS that someone also recommended but I have not tested it yet, so if anyone have any advice on how to use this as a GPS for a surface vehicle based in ArduSub I wil appreciate it.
Finally, is there a way to display the coordinates in the latest version of Qgroundcontrol? I just see the compass and the gyroscope, but no coordinates.
Thank you in advance
