"I have been using similar system already two years. Also with RTK. The advantage comparing to pixy, is that it actually works in high dynamic environment, thanks to L1/L2 receiver. I tested a similar system to Pixy, also L1 only, both in RTK and…"
"I have exactly the same problem with my APM 2.6. My brand new board was working flawlessly during 10-15 flights and then it suddenly stopped working, luckily on a table. I lost all control and connection with MP. I was not able to connect it again,…"
"Very nice. I know that it's just the beginning but It would be good to show the performance with respect to a reference GNSS receiver (e.g dual freq, surv. grade) and also demonstrate its performance under some dynamics. I am afraid that the on…"
"Hi, sorry for my late response. I tuned the param. only a little bit. Even with default pids it flies flawlessly. I am still on the 2.91 but both altitude and position hold are rock solid. Firstly I had really problems to tune the alt. hold and…"
"I have a coaxial octo with APM, with Axi 2814/22, xoar 12x6 and E-prop 11x5 running it on 5 cells lipo. The total weight is 5kg. I fly only in manual mode and so far without any problem. I like how it behaves and I can directly compare it with my…"
"This is nice, but what is the absolute precision? 0.2 m GSD is one thing, but what is the RMS on the check points? You did not say anything about the UAV, if it was <10kg UAV and you used indirect orientation approach or big UAV with GPS/INS…"
"How does the processing quality stay in comparison for instance with Pix4D, which is considered as a gauge of performance of the UAV image processing? You are talking about the resolution but what about the precision on the check points? How many…"
"Nice platform and results. I am just curious, what do you mean by two years of intensive development? What is custom on it apart from the integration of APM into the standard model? It is not obvious from the video,
"I agree with Enoc, proper pre-calibration is still the key for a precise work. It might not be important if you are using poor zoom cameras but for instance with modern mirror-less cameras with fixed lenses it definitely makes sense. With the…"
"Ho do you identify the targets? Manually or automatically? Could you show us the positions of the cameras- did you stay only on the ground during the image capturing or did you also use something like a telescopic platform for taking pictures…"
"It is really nice machine, but it is definitely not the first developed 12-rotor copter. The price is just insane. $49 000 without equipment? Using cheap Chinese T-motors (I am not saying that they are not good), standard Xoar props, I do not see…"
