- This thesis serves to address the commonly over compensation of a natural occurring phenomena when developing various link budgets for satellite communication systems. This being Galactic Noise, coming from the galactic center. However, due to the rotation of both the earth and the galactic plane this means that no location on earth sees the center of the galactic plane constantly. Here it is proposed that a new analysis be conducted where depending on the location (latitude and longitude), time, earth’s tilt, satellite orbit, and frequency, a dynamic link budget will determine the amount of power to consider for transmission and reception of the corresponding systems. Documentation of the process will be explained throughout the text. Where the problem is thoroughly introduced, and evaluated. Preliminary data is expounded upon helping to show that there is a cyclic nature to this noise source. The area of research conducted is in that of the naval communication, focusing on the the UHF (Ultra-High Frequency) band. The design and implementation of the antenna used to collect the data and key points of inspection, with various setups being presented, as well as the curve fitting approach used to predict the appropriate adjustment of problems.
