Hello,
I have a few questions about the code for expressing the sensor position.
Does the accuracy decrease if I use the quaternion through the sensor internal data logger instead of using the quaternion expressed by integrating with gyr,acc through the 'MahonyAHRS' code?

file='220316 센서 DATA/X-50-10-2/NGIMU - 0038A56F/quaternion.csv'; %Make a quaternion value available for direct use
file_data = xlsread(file);
Quaternion = file_data(1:end,2:5);

for i = 1:length(Quaternion)
R(:,:,i) = quatern2rotMat(Quaternion(i,:))';
end

If I continue to use the hig-pass filter from that point when deriving the tilt-acc, will the accuracy deteriorate further due to excessive drift removal?

l look forward to your response
