Italian-Chinese cooperation in telecommunication and propagation experiments with the Sirio satellite
Abstract
Plans for joint Italian-Chinese telecommunications experiments using the Sirio satellite, launched in 1977 to study the effects of precipitation on the propagation of its 17-18-GHz uplink and 11-12-GHz downlink signals, are summarized. The plans call for transfer of the Sirio orbit from 15 deg W to 65 deg E, where it will be visible both in Italy and in China, and installation in China of a ground station comprising a 3-m-diameter antenna, a 52-dB-gain transmitter with EIRP 70 dBW, a 49-dB-gain receiver with noise temperature 23.8 dB K, one 2-Mbit/sec data channel, and two 64-kbit/sec SCPC data/voice channels. Experiments are programmed to study absolute signal attenuation, data transmission, and the operating characteristics of the satellite and ground systems; further applications such as synchronization of atomic clocks, facsimile transmission of newspapers, and video teleconferencing are being considered.
