For readers studying this subject, Dr. Agarwal highlights the strict regulatory frameworks governing satellite frequencies. The table below outlines the standard frequency bands used in modern satellite communication: Uplink Frequency (GHz) Downlink Frequency (GHz) Primary Applications 1.6 - 1.66 1.5 - 1.55 GPS, Mobile Satellite Terminals C-Band 5.925 - 6.425 TV Broadcasting, Weather Radar Ku-Band 14.0 - 14.5 11.7 - 12.2 Direct-to-Home (DTH) TV, VSAT Ka-Band 27.5 - 31.0 17.7 - 21.2 High-Speed Satellite Broadband Summary of Core Advantages
Satellites must serve thousands of ground users simultaneously. The book details the evolution of sharing satellite bandwidth:
A satellite sweeps out equal areas in equal intervals of time, meaning its orbital speed fluctuates—it moves fastest at perigee (closest point to Earth) and slowest at apogee (farthest point).
Detailed calculations for carrier-to-noise ratio, uplink, downlink, and atmospheric losses.
Satellite communication is a cornerstone of modern telecommunications, powering global broadcasting, navigation, and remote connectivity. For engineering students, researchers, and professionals, remains one of the most highly recommended textbooks in India.
Physical copies are widely available at affordable prices on platforms like Amazon and Flipkart, published by Khanna Publishers.
D.C. Agarwal is likely a well-known author in the field of electronics and communication engineering. The book "Satellite Communication" probably covers topics such as:
To prevent the powerful transmitted signal from interfering with the faint received signal, the uplink and downlink almost always operate on different frequency bands. Orbital Mechanics and Keplerian Laws
Global coverage for television, internet, and navigation.
To understand why this text is a staple in engineering curriculums, it helps to examine the core modules typically explored throughout its chapters. 1. Introduction and Orbital Mechanics
Dr. D.C. Agarwal’s Satellite Communication covers both fundamental principles and advanced engineering topics, making it ideal for university courses and technical competitive exams. The book generally focuses on the design, analysis, and operation of satellite communication systems.
