This Chapter describes the physical characteristics of RPS-1 device and some of experimental results of observations onboard CORONAS-F satellite. Semiconductor spectrometer registered x-ray radiation in the range 3–31.5 Kev. Detailed spectral and time characteristics of weak solar flares were obtained for the first time under relatively low solar activity conditions and at the satellite passage outside the Earth Radiation Belts (ERB). It was established that the increase of solar activity was accompanied by the hardening of the background radiation spectra (without flares). Observations of the nighttime Earth atmosphere visualized the ERBs dynamics (disruption of the northern radiation belt in summer 2002) in the period following the cycle maximum. The energy of the nighttime X-ray emission of the upper atmosphere caused by precipitating magnetospheric electrons did not exceed 8 keV. The energy of GCR contribution to this emission did not exceed 5 keV
