"Great stuff!
For the RTL, I suspect the APM code may need a patch to deal with such high altitudes. The default is to use the barometer for altitude, using relative pressure between the ground start and the current pressure measured by the…"

catching the drift in DCM
Started this discussion. Last reply by Andrew Tridgell Apr 17. 7 Replies 3 Likes
I've been working for a while to improve the ability of DCM in ArduPilot to accurately track gyro drift while at the same time making it less susceptible to noise. It is a delicate balance, but it is…Continue

Hi All,I just wanted to give everyone who is waiting for a 3DR 433MHz radio a heads up about a shipping delay. A few days ago I discovered an interference problem with the 3DR 433MHz radios that can…Continue

Gábor Zoltán replied to Andrew Tridgell's discussion ArduPlane 2.34 released"Also got a question! :)
Is it possible to make APM mix a little rudder to throttle?
It is very important!

Martijn van Gene replied to Andrew Tridgell's discussion ArduPlane 2.34 released"Hi guys,
Since firmware 2.34 I cannot connect to my APM2 through APC220.
I get a "Connection timeout" and there seems to be one frame of data being sent. The status info (attitude, gps etc) of that single communications burst is being…"
DeveloperAndrew Tridgell replied to Andre's discussion Geofence questions?
"Hi Andre,
If you have no control then that means the plane thinks it is outside the fenced area (either by GPS position or altitude). It will have switched to GUIDED mode and will be trying to fly to the fence return point.
The idea is to only…"

Thurmond Moore replied to Andrew Tridgell's discussion Welcome to the 3DR Radio forum!"Outstanding job on the Radios. I received mine today and connection and setup took less than 15 minutes including soldering on the header. I look forward to "playing" with it on my quad in the coming weeks.

Does it compensate it somehow? (Not crosstrack.) "

I would very much appreciate a tlog showing this "compass reversed" problem. I have heard from others that the problem exists, but nobody has sent me a tlog showing the issue. Please capture the tlog as follows:

new ArduPlane feature - geo-fencing
Posted on December 24, 2011 at 5:02pm 20 Comments 12 Likes
The dev team is delighted to give a Christmas present to ArduPlane users in the form of a new geo-fencing feature!
Geo-fencing allows you to define a GPS fence around your flying area, plus a minimum and maximum altitude. Within the fence you can fly ArduPlane normally in any mode…

Posted on December 3, 2011 at 5:33pm 12 Comments 4 Likes
I've been working on the ArduPlane code for the new APM2 boards for a while now, so I was delighted to watch it loitering above my local flying field today for the first time. I'd flown it once before two weeks ago, but that was a very short flight as I had the aileron controls reversed (I don't have much experience with elevon planes!), so it was quite tricky to steer. It 'landed' in a tree…
ArduPilot automatic testing system
Posted on November 11, 2011 at 1:39am 17 Comments 11 Likes
The development team is always trying to find ways to improve our testing and the quality of our code. We've recently add a new automatic testing system that should help a lot with finding bugs and ensuring that the huge range of features that we have added (and plan to add!) to the code keep working.
If you have a look…
