In this study, the laser tracking system was introduced. In order to capture the target in a finite
area, the laser tracking system was first given a moving speed in the horizontal direction to make that the
target and laser tracking system were stillness in horizontal orientation relatively. The scanning pattern was
raster scanning. The smallest acceleration of the driving motor of the theodolite must be 8.5º/s2 in order to
make the target to be still on the area of pointing beam spot in the course of acquisition and tracking. When
the numerical value of eccentricity that the target departed from the center of laser beam spot was bigger
than a planning one, the motor compensated the eccentricity and pointed the target again. The driving
motor of theodolite compensated the eccentricity by an acceleration, uniform motion and speed-down
process. The minimum demanding acceleration was 5.72º/s2. So the acceleration of the motor of laser
tracking system was 8.5º/s2.
Key words: Acceleration , acquisition, motor, scanning, tracking, ,
