Abstract : An analysis of the control system for the Electro-Optical Surveillance Telescope at Cloudcroft, New Mexico, is presented. The tracking accuracy of the system is evaluated in terms of the limitations imposed by the dynamics of the control system, deflections of the telescope structure, and stability of the target sensing system. Analytical and digital simulation techniques are used to fix the parameter values and determine the effects of the system component non-linearities. Detailed analyses concerning the TV sensing system and the telescope structure are presented. Methods to correct or compensate the major error sources are discussed, and a test procedure is outlined to measure the magnitudes of the errors. The mechanical system analysis and the digital simulation program are included as appendices. (Author)
