Telemetering in the space program of the 1970's.
Brief review of the history of telemetering since the end of World War II, and discussion of telemetering needs and trends of the 1970's and 1980's. The shift in emphasis from quantity of flight equipments having relatively short lifetimes to quality of flight equipments having very long lifetimes is shown to characterize the main change from the 1960's to the 1970's in telemetering needs. Looking to the 1980's, the possibility is envisioned of the establishment of orbiting space stations capable of generating 1 to 10 trillion digital bits per day.
