  • It has just been suggested to me to manually do the magnetic declination. What is the GPS_SBAS_MODE?

  • If using Ardupilot, check out GPS_SBAS_MODE. "Disabling SBAS may be worthwhile in some parts of the world where an SBAS signal is available but the baseline is too long to be useful"

  • That's a good point, unfortunately I'm by myself at the moment and it's nightime with kids running round the street letting off fireworks so I can't drop it off down the street and come back to the computer to see. I'll have to do it tomorrow. One thing I did notice although it probably has no bearing on it, is that the image used in mission planner is an older one than that I'm using in Google Earth. I'm wondering if there is a setup I've missed in Mission planner. I've recently updated mission planner, but I don't know if this problem was there in the previous version. Sorry, sounds like I'm rambling.

  • Heh, I can understand redundancy, but that seemed excessive... And a completely different set of potential problems. Is the offset consistent? Or in other words, are you sure they are reading, and not just reporting a last known position? If YOU move some distance (100 ft or meters, whatever), does the pixhawk also report it?

  • LOL. No, they where all activated separately and none were operating together. I noticed the problem with one, then tried the other two in turn all resulting with the same Long and Lat position. So although they were all totally independent they did give me exactly the same location position.

  • 3 GPSs together? If so, what happens when you try one at a time? Two at a time?

  • Hi Guys
    I have a curly one that I can't figure out.
    I have just noticed (before I was about to do my first full autonomous flight) that all three of my pixhawks GPS's although different makes read exactly the same for my location, however they are all reading an additional 28deg 33'71" long and 12deg39'05"lat compared to both my iPhone GPS and Google Earth location.
    It has me totally stumped. Am I missing something really obvious here? If I program them with any waypoints, I'll never see them again.
    Love to hear any and all replies.

  • hi,I am a Chinese user of pixhawk. For some reason, I cannot watch the video on the pixhawk site. So I don't know how to connect the signal lines of the pixhawk airplane. Is there anyone who is willing to send a picture which can tell me how to connect these lines.My E-mail is I spent several days to calibrate the throttle. at last I found the throttle is No.4 output signal but not No.3. Then I got a new problem. I found there was no signal in No.3 output.I don't know why.thanks for help.   

  • thank you

  • My generic does exactly the same and it works fine.

Flashing in Pixhawk

Hi everyone,Recently I've got my first pixhawk CUAV v5+. I'm amazed to see one thing that through one USB port only we can flash code and read the logging data. To understand how is it working I started looking schematic but didn't understand anything. Can someone please tell how is that working?
