	; '''7. Increased demand for satellite communications''' : A need for improved communications for '''Apollo''' and a developing demand for commercial satellite communication from Perth led to the construction of '''OTC 2''' at Carnarvon in mid-1969, a 32m parabolic dish connected by coaxial cable to Perth. '''OTC 1''' was now released for maintenance and operations on the Intelsat network for tracking, telemetry, and command - monitoring the various communication satellites viewable from Western Australia.		; '''7.
