Is there any information available about how closely the two barometers in an Orange Cube should report pressure/altitude?
In one of my Orange Cube copters, I get a difference of about 2 feet.
This graph shows the reported altitude from Baro-0 and Baro-1 along with the altitude reported from my Lightware LW20 lidar. (the blue line)
Although I’ve not read anything about this specifically, my guess is that the ArduPilot EKF uses the available altitude data and synthetizes a value used in operation. In my experience to date - this produces great results.
But as reference, how much variance between barometers should alert us to possible problems?
