Reducing Energy Consumption in CubeSat Missions: The Integrated Antenna Approach
Abstract
One of the future challenges of increasing the harnessed solar power is efficiently using the CubeSat sides. One of the approaches is using integrated antenna systems with solar panels or payloads. This study proposes a new approach to using integrated antenna systems in remote sensing missions. In this approach, due to the integration of the antenna system with payload (in our case, with the camera), it is possible to achieve a significant increase in power generation. Calculations are performed for cases when the antenna system is integrated with the optical system (α = 0°), which means that they use the same plane. In the second case, they are separated by an angle of α = 90°, and in the third case, when they are pointed in opposite directions (α = 180°). In the case of α = 0°, where the camera and antenna module are aligned co-axially, there is no energy expenditure for CubeSat orientation. However, in the other two cases, energy is required for rotation and maintenance of the specified orientation throughout the entire duration of the satellite's flight over the ground station, amounting to 111.99 mW when α= 90° and 44.33 mW when α = 180°. This study is significant because it provides a data-driven approach to CubeSat design, emphasizing the importance of camera and antenna alignment in improving operational efficiency. By demonstrating how optimal configurations can lead to faster response times and reduced power consumption, the results can inform future mission planning and improve the overall effectiveness of small satellite operations.
