- STEP FREQURNCY RADIOMETERS: (Background)
Many spacecraft were launched from 1962 thru 1973 to record
solar and cosmic radio bursts. The spacecraft carried receivers
for various frequency ranges, and collected data intermittently
over those years. Some of the spacecraft were intended
primarily to observe cosmic sources, but solar bursts were not
excluded. Many data sets from these space missions are held at
NSSDC (National Space Science Data Center). These radiometers
were of use on these space missions.
