Try LPS+FLOW TDOA2 and TDOA3

Post by arix » Thu Jul 26, 2018 3:37 am

Hello !
I have made node,deck,cf2 and flow . I want to use them to fly. I use 8 node to make position system and i both use flow deck . I have try tdoa3 and tdoa2. Both of them have good position when cf no fly. And i use python lib to hover (setpoint commander) .
problem:

1. lps+flow+tdoa3 hover it can't fly. It will fly to everywhere. i find the data will drift.
2. lps+flow+tdoa2 hover it can only hovering about 5 seconds and then data will drift too.
3. lps+zranger+tdoa2 it can't hover too and will drift . kalman data not drift . i think maybe pid problem? and i change using millenger's position pid, but also dirfting. i only change position pid (not include velocity pid). On the other hand, i print xyz data and zrange data. when cf drifting, the data is actually near the hover point. i don't now how to explain it .

my hardware both made by myself . it can be hardware problem?



Thank you!
