The satellite radio link is unique in telecommunications due to its beyond line-of-sight capability and broad coverage with common characteristics. Because service can be predicted with good certainty, link budgets are the standard tool for designing and assessing satellite communications transmissions, considering radio-wave propagation, satellite performance, terminal equipment, radio frequency interference (RFI), and other physical layer aspects of fixed and mobile satellite systems. The format and content of the link budget, derived from basic equations and wave propagation properties, must be understood by engineers and managers with design and operation responsibilities.
This three-day course reviews the principles and use of the link budget along with hands-on training, for one- and two-way transmission of digital television; two-way interactive services using very small aperture terminals (VSATs); point-to-point transmission at a wide range of data rates; and interactive communications with mobile terminals. Services at UHF, L, S, C, X, Ku, and Ka bands to fixed and mobile terminals are considered. The course includes several computer workshop examples to enhance participants’ confidence in using software tool SatMaster and to improve their understanding of the link budgeting process. Participants should gain confidence in their ability to prepare link budgets and their facility with the tool. Software can be provided for use during the course only.
