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

The definition of a space station according to FCC Part 97 is specifically designated as an amateur station that is located more than 50 km above the surface of the Earth. This classification helps to distinguish amateur stations that operate in space from other types of satellite operations. The significance of the 50 km threshold relates to the boundary of space, which is generally recognized internationally.

This definition is crucial for amateur radio operators because it sets the parameters for what constitutes a space station in the context of amateur radio licensing and operation. Amateurs can operate satellites under specific rules, and understanding that a space station must be designated to operate at such altitudes is important for compliance with regulations.

While satellites and relay systems are integral to amateur radio activities, the definition limits the term "space station" specifically to those stations that are beyond 50 km. Thus, references to any satellite or manned satellites do not align with the specific legal definition provided in the rules governing amateur radio operations.
