Hi
I am trying to enable the wind estimation feature through Mission Planner, I went through the page Windspeed Estimation and Baro Compensation — Copter documentation, in the section " Viewing Windspeed and Direction in Real-Time" it says “once enabled”, how to enable this?
drone firmware version : Arducoptor V4.3.1
Mission planner : 1.3.79 build 1.3.8378.24878
I suppose with the BARO1_WCF_ENABLE parameter.
Thank you for the reply!
I checked BARO1_WCF_ENABLE is 1, but I still don’t see windspeed and directions in MP Quick.
I also checked EK3_DRAG_BCOEF X, Y MCOEF all set with values.
I am wondering if there is something else I need to set up to enable the wind estimation?
I admit I have not tried this feature. There is a video abut it from Mr. Riseborough:
Wind estimation
Thank you for providing the video, I also went through this when reading that webpage.
I set up all coefficients mentioned on the page but seems no data change or transmission in both wind direction and wind speed…
Are you using ArduCopter 4.3.2-rc1 ? You should.
Hi
Thank you for responding!
Is it possible to enable this in FM version 4.2?
I updated a CUBE Black to the 4.3.2-rc1 version, and also put
BARO1_WCF_ENABLE as 1
EK3_DRAG_BCOEF X, Y MCOEF with some values.
EK3_ENABLE = 1
EK2_ENAVLE = 0
AHRS_EKF_TYPE = 3
I still don’t see any changes in MP Quick wind direction and wind velocity, I am wondering if this feature only transmits data when the drone is flying?
Yes, only when flying.
Solved my issue, thank you very much!
I am very interested in feedback please - how much difference did the wind estimation make?
Did the baro compensation improve altitude performance - for example many people report a drop in altitude as the copter picks up speed, and a recovery of altitude as it comes to a halt.
I will update the feedback in the following weeks once I done more flight tests, will update here
I have been experimenting with the baro comp for fast flying, so far the height errors seem small so it is difficult to judge whether this feature is useful or not. I added Z-axis comp in 4.4
The wind estimation (no bara compensation) can be enabled:
EK3_DRAG_BCOEF X, Y = values you computed
BARO1_WCF_ENABLE as 1
EK3_ENABLE = 1
EK2_ENAVLE = 0
AHRS_EKF_TYPE = 3
Also, this feature even worked on Arducoptor FW 4.2.3, and also higher version 4.3, and 4.4(dev).
The wind estimation real-time results are available in QUICK, also in MAVlink inspector telemetry, WIND section is there.
Didn’t use baro compensation in my tests.
hii sir ,wind speed estimation and baro compensation working well or not? because i am working on that in latest version 4.5.3
The latest version is ArduCopter 4.5.7-beta1
but sir i am using 4.5.3 version
Then that is not the latest version like you described above.
Anyway, version is relative unimportant if the parameters are correctly configured.
Are they correctly configured?
ha sir i configured correctly .i am providing values also .my drone weight is 27kg accordingly
EK3_DRAG_BCOEF_X = 0.000124
EK3_DRAG_BCOEF_Y = 0.000132 ,
EK3_DRAG_MCOEF = 0.108 ,
BARO1_WCF_ENABLE = 1
[
BARO1_WCF_FWD=0.2
BARO1_WCF_BCK= -0.1
BARO1_WCF_RGT=0.3
BARO1_WCF_LFT=0.4
BARO1_WCF_UP=0.15
BARO1_WCF_DN= -0.14
]
How did you measure those values? Which process did you use? Do you have pictures? Do you have log files?
