Abstract

In May 1976 experiments were carried out in which 60 Mbit/s signals, generated by equipment constructed in Research Department, were transmitted through the Indian Ocean Intelsat IV satellite from the UK Post Office earth station at Goonhilly Downs, Cornwall. An outline of the experimental equipment is given together with a description of the transmission tests. Several interesting facts which emerged are discussed, mainly concerning the need for scrambling and the error performance.
