Introduction

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 must be understood by many engineers and managers with design and operation responsibilities. SatMaster is a highly-recognized yet low-cost PC-based software tool offered through the web by Arrowe Technical Services of the UK.

This five-day course reviews the principles and use of the link budget along with hands-on training in SatMaster, the latest version, 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 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 SatMaster. Examples from the class are employed as time allows. The course notes are provided.
