The small transmitter receiver stations in the Sirio experiment

Experiments related to the utilization of 3m antenna transmitter receiver stations are discussed. The stations can transmit or receive via the Sirio satellite either 64 k bit/sec or 2.048 Mbit/sec data rates from or to similar stations or large antenna (17m) stations. System operation was tested using large antenna transmitters and small antenna receivers. With clear sky conditions a 0.0000001 error rate is feasible. The influence of rain events with alternations of the order on up to 12 dB is discussed.
