Energy-Efficient Design for Satellite Communication: Challenges and Opportunities

Energy efficiency is becoming an increasingly important consideration in the design of satellite communication systems. With the rapid expansion of satellite constellations and the ever-growing demand for high-performance communication services, the need for energy-efficient satellite systems has never been greater. This review aims to analyze the key components and strategies for energy-efficient design in satellite communication systems, considering various technological innovations and approaches in the field. The paper examines the role of power consumption in different segments of satellite systems, including ground stations, on-board payloads, communication links, and satellite architectures. Furthermore, we explore optimization techniques, such as adaptive power control, power-efficient coding, and the integration of renewable energy sources, to reduce energy consumption. We also discuss the environmental and economic impacts of energy efficiency improvements and propose recommendations for future developments in this area.
