Results/More Information

The obtained results correspond to the data existing in this field calculated during Salyut and Mir station operations. Angular misalignments of the sensing axes of devices by approximately 1 - 2° due to ISS hull deformations occur just as they did on previous stations.

Nevertheless, the results obtained in the course of Privyazka enabled the development of corresponding mathematical models and the obtained measurements processing methods in order to determine ISS hull deformation, and device and system misalignments aiming to increase the accuracy of determining their orientation in the reference coordinate system for the high-quality analysis of scientific experiments conducted on the ISS.
