Summary of the subject: In this educational discipline, the classification of measuring equipment is considered and, depending on the performed functions of information and measurement systems, the principles of building a measuring system, an automatic control system, and a technical diagnostic system are given. The main attention in this discipline is paid to telemetry. Therefore, the purposes and tasks of radio telemetry, the structural diagram of aircraft, the main characteristics and general requirements and information about errors and their causes are considered. Classification of radio telemetry systems according to channel separation methods, features of modern construction and principles of construction of systems with time, frequency and code separation of channels are given. A selection of the main parameters and their advantages and disadvantages is also given. A comparison of systems with code, time and frequency division of channels and the principles of building adaptive radio telemetry systems are also presented.
