Servo Performance Parameters of the Deep Space Network Antennas
نویسنده
چکیده
The performance of an antenna control system is evaluated using performance parameters such as settling time, bandwidth, steady-state error in rate offsets, and antenna root-mean-square servo error while tracking in wind gusts. The performance parameters are measured in the field or obtained through analysis and simulations. Limited access time to antennas, incomplete test equipment, limited test/analysis time, and partial models do not allow for determination of all the parameters. However, field practice and analytical results indicate correlation between them; hence, even the incomplete knowledge of the performance parameters would allow for estimation of the missing ones.
