Key Concepts

Propagation Delay

Propagation delay is the time it takes for a signal to travel from the sender to the receiver, calculated by dividing the distance by the speed of signal propagation (typically, the speed of light). This concept is critical when analyzing communication systems because it directly affects the overall delay observed in data transmission.

Speed of Light

The speed of light, approximately 3 x 10^8 meters per second in a vacuum, is a key constant used in calculating propagation delays for long-distance communication like satellite links. It serves as the basis for determining how fast signals can traverse the considerable distances to and from satellites.

Satellite Orbits

Satellite orbits, categorized as GEO (geostationary), MEO (medium Earth orbit), and LEO (low Earth orbit), denote different altitude ranges and operational characteristics of satellites. Each orbit type offers a distinct balance of coverage area, latency, and signal delay, which is crucial for understanding trade-offs in satellite communication systems.

End-to-End Transit Time

End-to-end transit time refers to the total time required for a data packet to travel from its source to its destination. In satellite communications, this time is heavily dominated by the propagation delay caused by the large distances involved, especially in higher altitude orbits like GEO compared to LEO or MEO.
