Recommendation: For a proper study experience, obtaining the printed edition or a licensed digital copy is highly recommended, as it ensures you have high-quality diagrams and error-free equations essential for solving link budget problems. satellite communication by dc agarwal pdf
Satellite Communication " by Dr. D.C. Agarwal is a cornerstone text for engineering students and professionals, providing a comprehensive technical foundation for understanding how information is transmitted via artificial satellites. Core Concepts Covered
The book follows a logical progression from fundamental orbital mechanics to complex link design and modern applications:
Evolution and Principles: It traces the growth of satellite technology from early passive reflectors to high-capacity active relay stations that amplify and process signals.
Orbital Mechanics: Detailed explanations of Kepler's Laws and the dynamics of different orbit types, including LEO (Low Earth Orbit), MEO (Medium Earth Orbit), and GEO (Geostationary Earth Orbit). If you find a genuine copy of the
Satellite Subsystems: Technical breakdown of critical onboard systems like TT&C (Tracking, Telemetry, and Command), power supply (solar arrays and batteries), and the communication payload (transponders and antennas).
Link Design & Multiple Access: Mathematical foundations for link budget calculations (signal-to-noise ratios) and techniques that allow multiple users to share a satellite, such as FDMA, TDMA, and CDMA. Key Technical Parameters Orbit Type Altitude (approx.) Typical Use Case LEO 100–500 miles Satellite phones, low-latency data MEO 6,000–12,000 miles GPS and navigation systems GEO 22,282 miles Direct-to-home (DTH) TV, weather monitoring Modern Applications
Agarwal's work remains relevant by highlighting how these systems enable global connectivity in areas where terrestrial networks (like fiber or microwave towers) are impractical:
