Abstract
Ka-band downlink data from the Juno spacecraft were analyzed in order to characterize the performance of carrier signal-to-noise density ratio measurements relative to expected link budget performance. Data were acquired from the three DSN tracking sites (Goldstone, Canberra, and Madrid) between 2013 and 2023. Anomalous observations, defined as those below an adverse link budget minus an additional 4 dB, were itemized by stations, sites, and years; and furthermore, characterized by correlating with event data from monitor data (e.g., weather) and Juno radio science reports. The Juno Ka-band statistics were integrated with those derived from previous studies involving the Cassini, Kepler, and MRO spacecraft Ka-band downlinks. Such statistics are useful to future missions that may be considering incorporating a Ka-band downlink on their spacecraft.
