Communications Satellite Corp. Laboratories and Telesat Canada had recently completed joint field tests of the transmission of digital data through Canada's Anik 1 communications satellite (launched 9 Nov. 1972) , ComSatCorp announced. Data were transmitted at 67.2 megabits per sec, believed to be the highest rate ever transmitted by satellite. The high rate allowed two digital TV communications system color channels to be carried through a single transponder. The tests confirmed previous system analyses and proved the ability of satellites to transmit the equivalent of 100 newspaper pages in one minute. (ComSatCorp Release 74-22)
Communications Satellite Corp. filed proposed rates with the Federal Communications Commission for a new medium-speed digital-data satellite service called DIGISAT, to provide digital data channels between the U.S. mainland and Hawaii. The proposed monthly rate to international common carriers would be $2700 for 2.4 kilobits per sec, $3000 for 4.8 kbps, and $3900 for 9.6 kbps. Expansion to European points was expected later in the year. (ComSatCorp Release 74-21; ComSatCorp PAO, inter-view)
