CONCLUSION

To avoid service loss of implication for the Earth station inclination tracking, the earth stations need to track the satellite following the daily sinusoidal movements. If you are located on the same longitude as the satellite the north-south daily movement will be up and down. If you are on the equator then all the satellites are in a straight line across the sky from east to west, via directly overhead. North-south movement of all these satellites will be a sideways movement. Anywhere else and you have daily diagonal movements to content with, which means using two motors for an azimuth-elevation mount or a declination only motor on a polar mount dish.
