I'm trying to arm Starling without GPS and have calibrated the VIO camera, but QGC just shows "MAV_CMD_COMPONENT_ARM_DISARM component temporarily rejected" without any other messages when I try to arm it in position mode. I didn't see any useful logs when I ran "voxl-px4 -d" too. 

I tested that I can arm it in manual mode, although I have never successfully armed it in position mode before. Even when I tried with GPS, it kept giving me preflight failures (GPS speed accuracy, drift,etc.).

For this case without GPS, I'm running the following services

I can see that qvio is running

The mavlink messages are also being sent (mavlink_to_gcs)

So I'm not sure why it doesn't arm?

voxl-version: (I just realised the voxl-suite doesn't show 1.0.0? I had re-flashed VOXL SDK 1.0 on this previously)

@kerct did you remove the GPS? It is showing errors related to GPS

You can upload your PX4 log to logs.px4.io and it will likely tell you
