any Pixhawk issues at high latitudes?

Posted by Robert H Fraser on November 19, 2014 at 10:42am

Hi all -

 

I am wondering if anyone here has experience flying a Pixhawk-based multicopter at higher latitudes in the Arctic.  We are purchasing an octocopter with Pixhawk and 3DR uBlox GPS for use in surveying around Tuktoyaktuk, NWT next summer (69.4d N and a 24d magnetic declination).  Last summer, we had no problems flying a DJI NAZA based hexacopter up there after calibrating the compass and reorienting the GPS puck to 24d east (it toilet-bowled badly before turning the compass)

 

Besides possibly calibrating the compass using Mission Planner once we get up there, are there any other issues we need to think about?  I notice that Pixhawk/MP will automatically compute local declination once it achieves a GPS lock.

 

Thanks,

Rob

    Short answer; no
    I live in Tromsø, and have been flying much far beyond that.

      That's good to hear, Andre.  Despite our successful flights last summer, I have read about numerous issues using DJI's Naza and GPS at high latitudes.  In fact, the Naza-M manual goes as far to say that the "Compass module CANNOT work in the polar circle"
