we are having a problem with our multicoper
it is a Tarrot 650 ironman, with 17" props and a Pixhawk 1 with px4 software.
most of the time it is flying just fine. But then all of a sudden, it it will go completely crazy and freak out. as you can see in the logs provided at 1:38, it drops about 10m meters out of the air. and then recovers.
it gave a no global position error and [lib__ecl] EKF GPS fusion timeout - reset to GPS, and started beeping, so we think there may be a problem with the GPS
hope someone can help.
here is the log: https://logs.px4.io/plot_app?log=f4cc8c37-068c-4537-91ae-43313a89bd04
and here is another one where it gives the same error: https://logs.px4.io/plot_app?log=e96bd429-0260-476c-a6ec-d7ff9ded233e
