The variations of the intensity and spectral distribution of the EUV and x-ray solar fluxes from the whole disk in the wavelength range 0.1 - 134 nm are the main reason of changes in all upper atmospheric and ionospheric parameters and one of the principal factors in the solar-terrestrial relation changes. However the permanent monitoring of the solar EUV and soft x-ray radiation (0.8 - 120 nm) is absent at present. In this paper the recent advances in the elaboration of the topical-electronic apparatus complex for the permanent space patrol of EUV and soft x-ray solar radiation are discussed and optical schemes of solar spectrometers of grazing and normal incidence with diffraction gratings and also their energetic characteristics are presented.
