Applications of Satellite e. Navigation

Applications of Satellite f. Search and Rescue

Applications of Satellite g. Telecommunications / Telebroadcasting

Applications of Satellite h. Interactive Education

Applications of Satellite i. Sea Research / Scientific Explorations

Advantages of Satellite Communications Wideband Capability / Wide Area of Coverage Superior Reliability Direct Services to Subscriber’s Premises Point to Point and Point to Multipoint

Disadvantages of Satellite Communications High Initial Investment Short Life Span; 7 – 10 years Expensive Maintenance Very Dependent on Reliability of Launch Vehicle Require High Investments on Earth Stations Subject to Interception and Jamming by Enemy Forces Signal Propagation Delay / Delayed Response Time Risky Launching / Failures in Attaining Proper Orbit

Satellite Subsystems Payload – actual user information conveyed through the system Bus Transmission – includes control mechanisms that support the payload operation
