Maybe I missed it, but I could not find a specification of g - the gravity magnitude - that is used for scaling specific force values of BMI08x IMU. I would like to convert the values to m/s^2 and I would like to know the conversion factor, that is the magnitude of g. Can somebody point me to a documentation where g is defined? Thanks!
Solved! Go to Solution.
I am suprised that nobody else came up with this question. To my understanding, knowing magnitude of g would allow the correct conversion to SI units. For example, gravity magintude of certain Analog Device IMUs is not 9.807 but 9.798 m/s^2 depending on the calibration site. I am wondering, if this is the case for Bosch IMUs as well. Or if it is relevant at all for this type of IMUs.
A similar question was actually briefly discussed here. For most applications, using the standard gravity value won't have a significant impact on the application performance.
Hm, could I measure the conversion factor, that is g magnitude? Probably not, because I have no knowledge about the run-to-run biases. When, what can I do? Any suggestions?
Hm, in case of ADIS, it is only 0.1% deviation from 9.807 m/s^2 standard value. Probably not relevant considering all the other errors of the sensor. Still, for completness and consistency, I would like to know the actual conversion factor, because g is not an SI unit. Somebody out there who can help?
