Dead-weight deformation monitoring of revised Cassegrainian antenna

摘要

This paper introduces the setup of the Remote Coordinate Measuring System (RCMS), which uses two T3000 informatic theodolites. The system data recording module is on-line storage but off-line operation. Angle measurements form two T3000s are transmitted automatically to a Wild GRE4, which store the observational data for later analysis. Using the RCMS, authors check the dead-weight deformation of a revised Casse-Grainian antenna, with a 25-inch diameter. The results indicated that the RCMS can monitor the dead-weight deformation when the antenna is in certain positions.
