Abstract
Dual carrier transmission from a deep space station can result in receive-band interference signals. Investigations have been conducted at the Mars Deep Space Station to determine the impact of this interference on telemetry and doppler data in terms of the carrier-to-interference power ratio. These investigations were limited to uncoded data at 2048 bits/s and to a fixed (near zero) doppler frequency. In general, it is seen that for carrier loop margins near 20 dB (typical of Viking orbital operations), the presence of detectable receive-band intermodulation interference will produce detectable data degradation.
