The Deep Space Network (DSN), managed by the Jet Propulsion Laboratory for NASA, is used primarily for communication with interplanetary spacecraft. The high sensitivity required to achieve planetary communications makes the DSN very susceptible to radio-frequency interference (RFI). In this paper, we present an analytical model of the performance degradation of the DSN sequential ranging subsystem in the presence of downlink CW interference in the ranging channel, and show a trade-off between the ranging component integration times and the ranging signal-to-noise ratio to achieve a desired level of range measurement accuracy and the probability of error in the code components. Numerical results presented illustrates the required trade-offs under various interference conditions.
