Satellite Communications Payload and System

Description

Electric Vehicle Machines and Drives K. Cable System Transients Akihiro Ametani. Domain-Specific Modeling Steven Kelly. Wireless Communications Andreas F.

Back cover copy Covers both payload systems engineering and applied communications theory It takes more than ten years on the job for a communications-satellite payload engineer to "know" the payload. Satellite Communications Payload and System accelerates that learning.

It provides the information needed to design, develop, specify, analyze, and validate a payload that will work as part of the end-to-end that is, ground-to-space-to-ground communications system. It explores the technology of payloads currently on orbit.

This is the only book that: Describes the payload units at a systems engineering level, plus tells how they work. The units are antennas, low-noise amplifiers, frequency converters, filters, high-power amplifiers, and units particular to processing payloadsSufficiently describes what the on-orbit environment does to payload electronics over the satellite's lifetimeConnects communications theory to the details of payload and link behaviorContains a probabilistic treatment of multi-beam payload performance with atmospherics, over lifeGives tips on how to ensure quality of end-to-end communications system simulation Satellite Communications Payload and System is the ideal guide and reference for systems engineers of the payload or the end-to-end communications system, at all career stages.

It is an important resource for satellite customers, proposal writers, payload unit engineers, spacecraft bus engineers, and control center engineers who want reliable payload information. It provides real examples for students of systems engineering, microwave engineering, space technology, communications theory, probability theory, and communications simulation.

She has twenty-six years' experience in satellite and ground systems and technology, twenty-three in communications, and three in navigation, at major corporations. Book ratings by Goodreads. Spacecraft Antenna Design and Performance.
