A system includes a first planetary gear set comprising a first sun gear, at least one planetary gear, and a first ring gear designed to rotate at a speed lower than an operating speed of rotating equipment. The system further comprises a second planetary gear set comprising a second sun gear, at least one planetary gear, and a second ring gear designed to rotate at a speed lower than the operating speed of the rotating equipment. The system further comprises at least one laser source installed on the first ring gear of the first planetary gear set and at least one laser receiver installed on the second ring gear of the second planetary gear set. The at least one laser source corresponds with the at least one laser receiver to measure alignment readings while the rotating equipment is rotating at speeds up to and including the operating speed.
