Abstract

Ka-band (32-GHz) monopulse tracking has been chosen for the upcoming NASA missions. This decision requires an increased pointing accuracy of the Deep Space Network antenna servo systems that are maintained in a noisy environment. The noise sources include wind gusts, encoder imperfections, and Block V Receiver (BVR) noise. This article describes the selection of the position and monopulse controllers for the improved tracking accuracy and presents the results of the linear and nonlinear simulations to confirm that servo performance meets the requirements.
