Noise Resistance Enhancement in Aircraft Navigation and Connected Systems

This book presents methods and algorithms to improve noise immunity of the navigation systems of civil aviation aircraft, operating on the basis of satellite radio navigation systems, as well as improving the quality of the transmission of navigation information by selecting a rational communication resource. The book provides for its productive perception both by specialists involved in the development and operation of radio electronic equipment, responsible for navigation and communication support of civil aviation aircraft, as well as by graduate students or senior students, since this book examines in detail the promising fields of development of these tools taking into account the need to comply with all requirements for noise immunity.
