[Paparazzi-devel] Engaging Auto2 without the ground station running ; Slew rate in Auto modes ; Aircraft response speed in Auto1

[BX Guan]

Hey guys, a few quick questions out of curiosity.

1) What is meant to happen if I engage Auto2 without actually running my GCS? I would assume that that's the same situation as a GPS and/or datalink signal lost. I know that the failsafe for GPS signal lost is configurable, but what about if the actual datalink is lost? Would I be able to say, have the UAV flying around in circles on standby by default every time I engage Auto2 (without actually running my GCS) or if say I put it on standby, then shutting down my software (to simulate a computer crash, for example)?

2) I was reading some old topics from the archive, wondering whether slew rate of throttle for Auto1 and Auto2 modes are still in effect? There was some discussion as to whether slew for Auto1 is necessary, so if it has been removed I'd like to perhaps know the reason(s) behind it.

3) I noticed that my UAV is capable of more robust movements in Manual mode compared to Auto1. It can make sharper turns etc. I was under the impression that the issue can be fixed by changing the maximum roll and pitch angles allowed in Auto1 mode, but it is still much slower even with an angle of 1.5rad for the roll, with the UAV not rolling anywhere to that degree. Is there another area that I should be paying attention to? Perhaps P gain for Roll and Pitch?


Thanks,
