If you experience the TB the telemetry won't give you much helpful information. If your calibrations are good and you have waited before launch to get good satellite connections, the problem can be either the GPS module or the Flight Controller. I will send you a PM.
. I did download and install UAV Toolbox tonight, the flight telemetry showed multiple compass errors right at the beginning, that I totally missed because I was messing around with other stuff. Will recalibrate the compass in the AM, will report the results when I have them.
@daved20319Uh, I have a sneaking hunch that the issue was my fault. I updated the TH and camera/gimbal FW last night, but didn't clear the Flightdata, which means I didn't have to re-bind bird and camera, then to add insult to injury, I didn't do the compass calibration this morning, either
One, possibly dumb, question that might have a bearing. I was flying around my shop, which is a 30' x 40' steel building. I never had the building between me and the TH, but I was flying next to it, and was standing within 20' or so when it started getting squirrelly. Contributing factor, or just coincidence? Thanks.

With RC stick input the FC will use the GPS information to compute the new lat/lon.
. Later.I don't think "the compass is there simply to tell the FC where the aircraft's nose is" is accurate. Say you wanted to fly due north. The ST16 would leave the GPs longitude values alone and increment the latitude and communicate the change to the H. But the H would not know which way to head unless the compass was calibrated to take into account the magnetic declination. If the compass value was incorrect it would start in the wrong direction, see the error in longitude and correct for it but there would be a need for continuous corrections until the new GPS value was reached. That's what I think.So if I'm following you, the compass is there simply to tell the FC where the aircraft's nose is. But once it starts moving, the GPS should be able to calculate the vector, and thus the heading, needed to get to the new coordinates, or am I still missing something? I can see it being a bit more complicated with a multi-rotor or rotary winged craft, since they can fly any direction as well as hover, but it still feels like a compass is somehow redundant. Or is that the real reason it's still there, if GPS goes out, at least a compass gives you the possibility of finding your way home via dead reckoning? Not trying to be argumentative, I'm genuinely curios and, obviously, still confused
