Satellites on the Air
December 1962 & March, April, May, and June 1963 Popular Electronics

December 1962 Popular Electronics

December 1962 Popular Electronics Cover - RF CafeTable of Contents

Wax nostalgic about and learn from the history of early electronics. See articles from Popular Electronics, published October 1954 - April 1985. All copyrights are hereby acknowledged.

By late 1962, the United States was launching new satellites at a very rapid pace. Many were destroyed on the launch pad, others never turned on once in orbit, still more turned on and operated in a crippled form and/or only for a small portion of their intended lifespans. It was a learning period for the entire satellite, rocket, mission control, Earth-based tracking stations, and the communications equipment that dialoged with the satellites. The "race" part of the Space Race moniker was literal. Popular Electronics, QST, Electronics World, and other electronics communications publications regularly printed a list of newly commissioned satellites. The lists presented here came from five different 1962-1963 editions of Popular Electronics. The feature was repeated for many years. Incidentally, the "mc" frequency unit used at the time was the common abbreviation for "million cycles per second." In 1960, the Hertz was adopted by the General Conference on Weights and Measures (CGPM) (Conférence générale des poids et mesures) to replace cycles per second (cps). About a decade was required to get most people to use Hz as the base frequency unit; old habits die hard.

The following satellites, launched by the United States and the Soviet Union, were reported to have beacon and telemetry transmissions as of October 10, 1962. The satellites are listed by their code names, according to frequency; because some transmit on more than one frequency, they appear more than once.

*Signal may be very weak

At least four more satellites are in orbit and may be transmitting. However, these are so-called "secret" satellites launched by the U.S. Air Force.

If you're interested in eavesdropping on satellites, and missed our June 1962 article on the NASA-136 converter, we recommend that you look it up. Easy to construct, this sensitive converter can intercept the satellites operating in the 136-137 mc. band .

*Transmits only while satellite is in sunlight - no battery power

**Transmits only upon command from ground stations - not during every pass

Satellites of the Soviet Union have telemetry and tracking transmissions in the 19.990 - 20.010 mc. band. Whenever a Cosmos series satellite is launched, check Radio Moscow for an announcement of tracking frequencies. Most Cosmos series satellites re-enter the atmosphere in 60-90 days. Cosmos 2, 5, and 8 are in orbit at press time, but do not seem to be transmitting.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
