For each run the .txt file is created with saved MRU data in the “data”
subdirectory. File name consists of s/n of MRU, indication what MRU angle
was tested (H – heading, P – pitch, R – roll), reference angle, reference
temperature, time of run. For example, file
"106A0016_H(38.22)_T(+27)_1831.txt" corresponds to data saved from the
MRU s/n 106A0016 at Heading accuracy test for target angle 38.22 at
18:31.
Also the file of the report like Accuracy_2010991830.txt is created
where numbers are year, month, day, hours, minutes of performed test.
there are averaged data for each MRU run at accuracy test. In the first
column of this file there is MRU s/n, second column is number of reference
angle starting from zero, 6
th
– 7
th
columns are averaged Heading, Pitch and
Roll measured by MRU.
