Satellite Link Budget

This course covers the fundamental aspects of satellite communication, starting from the concept of link budget in wireless communication to the intricacies of interference regulation by the International Telecommunication Union (ITU). The course delves into the power requirements in a wireless link, explaining how power is radiated from a point source and how it reduces with distance. It also discusses the different types of losses in a satellite communication system, including path loss, antenna misalignment, and feeder loss. The course further explores the concept of noise power and how it sets the threshold for minimum detectable signal in a receiver. It provides a comprehensive understanding of noise power calculation, noise figure, and noise temperature. The course also discusses the role of the antenna in receiving noise in addition to the signal and its characteristics. It concludes with a detailed explanation of the uplink and downlink in satellite communication, the concept of bent pipe transponder, and the regulation of interference by the ITU.
