How does the FCC define a space station in relation to amateur radio?

• A. A station within the Earth's atmosphere
• B. An amateur station located more than 50 km above Earth’s surface
• C. A ground-based control station for satellites
• D. A station that communicates with space agencies only

Answer: (B)

The Federal Communications Commission (FCC) defines a space station as an amateur station that is situated more than 50 kilometers above the Earth’s surface. This definition is significant because it establishes the boundary between terrestrial (Earth-based) and space operations in amateur radio. By designating this altitude, the FCC differentiates between typical amateur radio operations, which occur within the atmosphere, and those that involve satellite communications or other space-related activities. Understanding this definition helps amateur radio operators know when specific regulations and rules apply, particularly in terms of licensing, operation, and the use of frequencies. The elevation of 50 kilometers is also tied to the Kármán line, which is commonly recognized as the boundary of space, allowing clearer distinctions between typical radio communications and those conducted in space.
