Abstract:

The SOLRAD 9 satellite, launched March 5, 1968, carried instruments to measure solar radiation in the x-ray region from 0.1 to 60 Angstroms and in the far-ultraviolet from 1080 to 1350 Angstroms. These spectral regions are covered by a number of band-sensitive ionization-chamber photometers, Geiger counters, and scintillation counters. An aspect sensor was also included to measure the angle between the solar direction and view direction of the photometers for correction of photometer measurements in case of failure of the attitude-control system. The satellite transmits its x-ray and ultraviolet measurements in real time via an FMAM telemetry system operating in the 136-MHz band. Author
