Ted P replied to Ted P's discussion SITL on Linux just stops after about 20 minutes
"I looked at the logfiles (and attaching for reference). The SITL logfile is consistent with the Mission Planner logfile -- output just seems to stop at a point. The plane doesn't crash or anything like that.
I was wondering if something is going…"

As the subject line says -- I'm running ArduPlane SITL (Rascal) on a Linux box. It works great -- but after 20 minutes or so, it just stops -- I get "no link" in MavProxy. I am trying to find any logfile to see if I can deduce what might be…

"Jeff,

That looks to be about standard -- I'm getting similar results. Since my drone is far relative to the tracker, the GPS noise isn't too big of a deal, but it can be a problem if your vehicle is close to the tracker (worst case will be if it's…"

"Hi Linus,
I'm glad it worked for you. I've been meaning to test the tracker out with a virtual copter since it's possible to have the vehicle "fix" the location. I am trying to troubleshoot possible offsets in the tracker versus setting PID values.…"

"It's not clear if you are using a virtual tracker or not, but for my setup I am successfully using a SITL Arduplane with a REAL tracker. Depending on your tracker configuration there might be other parameters to tweak on the TRACKER. I also think…"

"Here's the changed file. You'll have to recompile the software according to these instructions:

Also, I'm not sure I fully grok your setup, but the tracker needs MAVLINK GPS messages to tell…"

"Paul,
I've modified v0.5 of the tracker to do exactly what you want, since we need to point to a specific GPS coordinate. All I did was to disable the auto-scan mode on loss of signal, and I just feed the tracker GPS Mavlink messages to get it to…"

"Is anyone running the tracker via a small computer like BeagleBone or RPi? I'm trying to get MAVProxy working on my Beaglebone, and have done so successfully, however the tracker module will not show up when doing a "module --list".

Thanks

"Seems to make sense, the closer your vehicle is to the tracker, the higher the gains would have to be on the tracker to keep up. A 10 yard motion close in is a much higher angular motion than 10 yards out. Increasing the gains can then add…"

"Hi Jakub,
It took a while to get a better grip on MavProxy, but the key is to differentiate between what is defined as a link and what is defined as an output. They are denoted by the direction of the arrows on my block diagram. The arrow points…"

"I have been spending a good amount of time with MAVPROXY, and while it's very powerful, as mentioned previously you can end up with a loop if you're not careful (my setup has 4 instances of MAVPROXY running).

With respect to the barometer altitude,…"

I am trying to get a shadow copy of all commands going from Mission Planner to my vehicle via MavProxy. To do so, I added a second link (using "link add") to MavProxy which I am routing to my monitor software. However, it seems that MavProxy will…

"Ed -- It's a pretty major kludge what I did, and also I don't have the time to learn GIT in order to upload stuff. Basically, there's a "location_valid" flag that gets set to false if GPS information IS NOT received within a timeout period. I just…"
