"I want to follow up on this, in regard to my Pixhawk having abrupt changes in course when in GPS modes. Based on analysis of logs and suggestions for different configuration and some shielding, it now has much better performance. The copter now has…"

"I'm not sure of the HDOP, that is prob in the log, but I usually have 10-13 sats within 10 seconds. Andy, I'm glad yours improved. I will try that and have results soon, too. Thanks for your suggestions."

"You are correct, Rejean. I was cornfused between the two. I noticed that POI do not clear when you do Clear Mission, so it might be good for remembering where one survey left off as you draw another.
Any idea why I have lost spline waypoints on 2 of…"

"When the mission program gets to the set POI cmd, the ship will face that point as the ship travels to the next waypoints. Set POI to location 0,0 to free the ship back to normal."

"Andy, I see similar things, were it boots up fine, but will not lock GPS until I unplug it and start over. Then it works fine. Have you tried that? As for the leveling, that is done when you arm it. Whatever angle it is when you arm is what it…"
