Has any one integrated the Tritech MicronNav unit through RS232 on the Blue ROV?
Im presuming its fairly simple but if someones done it, let us know please.
Also if you have, what navigation software have you used ?
Hi @real_kiwi -
This rather long thread ended up with a resolution to a bug in the Tritech software!
While that thread was dealt with in the old days of Companion OS, parsing an NMEA stream to show vehicle position on the map should be possible with BlueOS. There are two approaches, using the NMEA injector or parsing the messages directly with ArduPilot.
To better advise, can you share your goals for the BlueROV2 equipped with this payload?
A quick search also yielded this thread
Hi, has anyone setup the MicronNav 100 through the Cockpit app?.
Hi @Seair -
If you’ve correctly configured the MicronNav to be sending position information to ArduSub, and the vehicle knows its position, the map-view widget in Cockpit should display the vehicle on the map.
However, mission planning functionality is still in development and may not function as desired (yet!)
Hi Tony.
I’ve set Hub Port A to 232, 9600 Baud, ASC11 mode , tried all the Formats still nothing on Cockpit or in QGC.
The modem is just set up as a standard beacon, only taking power from the sub.
What I’m i missing ?
Cheers
Hi @Seair -
Can you share what parameters you configured in the autopilot? What NMEA messages is the MicronNav sending, at what rate?
What version of ArduSub and BlueOS are you running?
Hi Tony
4,1,2 Stable
Latest version of Blue OS
the hub offers all formats and baudwidths, been using 9600.
Would like to use Cockpit for this project tmorrow. but QGC will do as long as i have lat/lon on overlay
Cheers
Hi @Seair -
I believe you are missing some required messages - you need RMC, GGA, VTG, and HDT to be sent. You may need to configure them to be sent at a high rate as well.
If the NMEA injector doesn’t seem to do the trick, you can follow the instructions for setting up the udp input on Serial 2. This post has the details on that approach!
If you just need the lat/long displayed in a widget, and recorded in telemetry file that is played back with the video, taking a different approach and parsing the serial messages with Node-RED could also work!
