Analysis of Tracking Follower System of G171 Satellite Laser Ranger

In this paper the motion differential equations,transfer functions and frequency characteristics of the tracking follower system of G171 Satellite Laser ranger are analyzed and calculated.It also analyzes the linearity and dead band of the system.On the basis of these analyses,it indicates that theoretic and measuring values of the system's dynamic quality index are well consistent,and the system's steadiness and briskness are fine.
