The tools to be calibrated on the rate and position table don’t have typical mounting features, such as flanges or mounting holes. Instead, they attach to the working surface using a pair of angled magnets. At the same time, an accurate alignment to the rate and position table’s coordinate system is necessary for any IMU calibration.
Optimizing the number of units to be tested on the table presented a separate but related challenge. How could we fit as many tools as possible on the testing table without affecting the calibration outcome? That was especially tricky considering the shape of these tools was not conducive to a tight installation on the tabletop.
Finally, due to the nature of their interfaces, these tools could not pass their measurements through the rate and position table’s slip rings. Therefore, a custom solution was required for this aspect too.
