Abstract: |
Based on the development of a certain model CPA (Coarse Pointing Assembly), the technical difficulties in measuring the wobble error and the verticality of the arcsec level spindle are explained in this paper. The measurement principle, configuration and data processing method are introduced in the illustration of the CPA spindle test case. This measurement method is significant for development of the CPA, and can be applied to the similar space high-precision pointing and tracking mechanism. |
