Re: How to get compass data in arduino?

Just for me to understand. So, basically, you need the same what we currently already have for modem, also on the mobile beacon, right? Raw distances. And then you do the mathematics, filtering, etc. by yourself. Correct? Exactly! The Kalmann filter in the ardupilot code already does the triangulat...

Re: How to get compass data in arduino?

BTW, the coordinate system we see on the dashboard is following ENU (East, North, Up) coordinate system right? and not NED (North, East, Down) ?

Re: How to get compass data in arduino?

Okay Thank you!! Yes it is from the mobile beacon. How it works is that, these raw distances are inputted to the EKF of ardupilot which then computes the position of the vehicle! https://github.com/ArduPilot/ardupilot/blob/master/libraries/AP_Beacon/AP_Beacon_Marvelmind.cpp#L390 This is why :( Just...

Re: How to get compass data in arduino?

Hello!
Any possiblility of receiving the raw distances of the hedge to the stationary beacon?
Still waiting for this for the pixhawk integration of marvelmind :(

Re: Firmware and Params for autonomous flight (Link to firmware added)

Hey Debupt,

can you check this thread. I have opened up a post and there people will definetely help you out!

http://discuss.ardupilot.org/t/ardupilo ... cons/18677

BTW are you using MM as a beacon or MM as GPS?

Re: Firmware and Params for autonomous flight (Link to firmware added)

Hey Debupt, Yeah thats the problem of the NMEA protocol! you dont get an accuracy on the pixhawk end due! If i remember correctly you get around ~11 cms accuracy and that coupled with noise from MM will lead to this. That is why we are trying to use MM as a beacon but not a GPS, but still having pro...

Re: Firmware and Params for autonomous flight (Link to firmware added)

Interesting..RTL didn't work for us either. We were thinking that the parameters were messed up! Okay gonna give it another try in Auto and Guided mode.
Were you guys successful in Guided?

Re: How to get the original distance data with C lib?

Hello, Yes this feature would be helpful for the ardupilot integration also as the Kalmann filter expects raw distances to the hedge! right now we are calculating wrt hedge position! check out the comment here https://github.com/ArduPilot/ardupilot/blob/master/libraries/AP_Beacon/AP_Beacon_Marvelmin...
