dc.description.abstract During the descent phase of the Huygens Probe released from the Cassini spacecraft and inserted at Titan, the Deep Space Network (DSN) Canberra Deep Space Station (DSS) 43 (with its 70-m antenna) is being considered as a backup station to directly receive the Huygens Probe data being transmitted at 2.04 GHz. This study provides an assessment on the interference level from the major nearby transmitters operating in this frequency band. The minimum trans-horizon attenuations are calculated using terrain topographic data and the Trans-Horizon Interference Propagation Loss (THIPL) Computing Program recently developed based on ITU-R P.452, and the calculations take into account all propagation modes under a 0.1% of time exceeded. We find that there are five terrestrial transmitters within 100 km of DSS 43. Transmitter 1 is the closest to DSS 43, and needs to be coordinated to avoid interference. The rest of the four transmitters will not interfere with DSS 43. The interference levels from these transmitters are all below the DSN protection criteria of 99.9% of time en
