-Because a mathematically strict transformation to a regional reference system is not possible on the BNC server side when a significant scale factor is involved, the program follows an approximate solution. While <u>orbits</u> are transformed in full accordance with given equations, a transformed <u>clock</u> is derived through applying correction term
