The velocity measurement precision of sky screen was analyzed in this paper. Problems involving measuring distance between two sky screens and placement of sky screen will be discussed. Using tapeline to measure the distance between two sky screens would cause 5 kinds of error; using normal counter to measuring time interval would cause a “±1” pulse error. A few ways were brought forward to increase precision for measuring distance and time interval, which could eliminate the influence of human error. Those methods are controllable, simple and convenient. Applying those methods would increase the precision of velocity measurement of sky screen to a degree that would satisfy the requirement of testing.
