hi everyone,

I have two imu sensors, i want to know which of these sensors provide me the correct value? which of them are compatible with ENU convention? i don't know which of these sensors can be used in robot-localization pkg!!!

just to note that z axis in both imu is showing up! I would be grateful if someone helps!

@tom Moore hi, would you please guide me that which of these sensors are in ENU? and is appropriate to use in r-l pkg?

hi the second imu, shows z: 10.1418380737 in linear-acceleration, should not it be +9.8??
