abstract = {Space systems are composed of three Segments: Space, Launch, and Ground Segment. Although the first one is employed to achieve the mission objectives, a reliable ground station is a crucial resource for maintaining a mission in operational conditions. A Ground Segment can be implemented, considering higher or lower cost. It depends on the complexity of the desired system. This work aims to present a design process to implement a low-cost and low-complexity station, using Software-Defined Radio for receiving communications from space and monitoring signals from emitters on the ground. A simple use case employing Bifilar and Quadrifilar Helix Antennas for meteorological satellites is presented. Next, an example of an application in Electronic Warfare is presented, where the data fusion of data from space and ground emitters is suggested to provide geolocation information and identification through the d-interleaving process. The results show that a Ground Station can be developed with low complexity and low cost.},

abstract = {A Brazilian ground station network, DATASAT, utilizes Automatic Directional Antennas (ADA) for satellite communication. This research explores noise elimination within the ADA framework, focusing on Surface Acoustic Wave (SAW), helical, and cavity filters. By comparing signal-to-noise ratios with and without filters, the aim is to optimize ADA performance for reliable data transmission. This is crucial in today's environment with an increasingly crowded satellite population. Effective noise reduction improves communication efficiency, benefiting both DATASAT and the broader satellite operations community.},
