This study aims to compute the periodicities of solar and geomagnetic indices, such as the solar indice IMF-Bz, Dst, Kp, and AE, using the spectral analysis method. This approach offers a fresh perspective on the dynamics of Space Weather and its implications for satellite technology. The primary focus is on investigating the periodic changes in these indices through longterm, one-dimensional temporal Fourier Transform analysis, after the data has been smoothed by applying a sliding median filter. In a solar maximum year, such as 2001, the dominant period for the solar indice IMF-Bz aligns with the Sun's rotation period, which is approximately 27 days. Additionally, the upper and lower harmonics of this cycle have been identified in indices that reflect levels of geomagnetic disturbance, occurring at intervals of approximately 1 month, 3 months, and 6 months, as well as shorter periods of 1 week, 2 weeks, and 3 weeks, respectively.
