What is the FCC Part 97 definition of a space station?

The FCC Part 97 defines a space station as an amateur station that is located more than 50 kilometers above the Earth's surface. This definition is critical in understanding the operational parameters of amateur radio and the different classifications of stations.

The significance of the 50-kilometer threshold is based on the distinction between terrestrial and space operations in the context of radio communications. Above this altitude, a station qualifies as a space station due to its location in outer space, transmitting signals to and from Earth. This opens up unique opportunities for amateur operators to engage in satellite communications and experiment with radio technology in a space environment.

Understanding this definition is essential for amateur operators who may be involved in satellite communications, as it provides clarity on what constitutes a space station under FCC regulations. Also, recognizing the operational limits associated with space stations compared to other types of amateur stations enhances operators' abilities to comply with regulatory standards while exploring radio communications beyond just terrestrial applications.
