Thank you for yr reply. In fact, I did set the location where the tracker is as home. But probably due to many other reasons, the servos still don’t move.
By the way, you told me Oct last year to use SITL to test the tracker. I followed all the instructions in wiki, downloaded and installed MAVProxy, then when I came to install Cygwin 64-bit installer for my laptop, not all the packages required to select , according to the wiki, appeared. So I was stuck there last year.
I am not a developer, and thus no coding knowledge. Preparing my laptop to use SITL is a great challenge to me. It has been over 2 years since I started this AT “in the middle”project, without success. I will not give up, and still desperate to try to make it work.
To reply to your question in Oct 2017, as follows :–
“ Do you have a GPS connected to the tracker?
If not, it will assume a position somewhere on the equator and depending on where you live, this might be a long distance away from the position your vehicle reports. So even if you move your vehicle, the resulting radial change related to the tracker’s position is so small, you will not see any servo movement.”
The tracker is set as home at a location just few meters away from the vehicle. Out at the field, I fly the quad 4-5 meters above the tracker and over 15 meters across, the 2 servos still don’t move. I don’t know why.
You used u360gts to test the tracker. Does it work ? Can you provide more info ?
