*Question T1A07:
[97.3(a)(41)] What is the FCC Part 97 definition of a space station?*  

*Correct Answer is  C: An amateur station located more than 50 km above Earth's surface*  

### AI Response: (may contain errors)  

The correct answer to the question about the FCC Part 97 definition of a space station is:

**C: An amateur station located more than 50 km above Earth's surface.**

### Explanation of the Correct Answer:
- The FCC defines a space station specifically as an amateur station that is located in space, which is defined as being more than 50 kilometers (about 31 miles) above the Earth's surface. This definition is important for distinguishing between terrestrial and space-based amateur operations.

### Why the Other Choices are Incorrect:
- **A: Any satellite orbiting Earth**  
  This choice is too broad. Not all satellites are classified as amateur stations. The definition specifically refers to amateur stations, which must operate under amateur radio rules.

- **B: A manned satellite orbiting Earth**  
  While some space stations may be manned, the definition does not require the station to be manned. It can be unmanned as long as it meets the altitude requirement.

- **D: An amateur station using amateur radio satellites for relay of signals**  
  This describes a ground station that communicates with satellites, not a space station. A space station must be located above the specified altitude, not just utilize satellites for communication.

### Summary:
- The key takeaway is that a space station, according to FCC Part 97, is specifically defined as an amateur station located more than 50 km above the Earth's surface. Understanding this definition helps clarify the distinction between different types of stations and their operational parameters in amateur radio.
