Who may receive telemetry from a space station?
The correct answer is A: Anyone. Anyone may receive telemetry from a space station (amateur satellite). There are no restrictions on receiving satellite telemetry - it's an open transmission that anyone with appropriate receiving equipment can receive and decode. For amateur radio operators, this means you can monitor satellite beacons and telemetry without any special permission or registration. However, transmitting to satellites (uplinking) requires an amateur radio license. Understanding this helps explain why satellite tracking and monitoring is accessible to everyone, while transmitting requires licensing.
Exam Tip
Receiving telemetry = anyone can do it. Think 'R'eceive = 'R'egardless of license. Receiving satellite signals (including telemetry) is open to everyone. Only transmitting requires a license. No registration or certification needed to receive.
Memory Aid
"Receiving telemetry = anyone. Think 'R'eceive = 'R'egardless of license. Open to everyone - no license, registration, or certification needed. Only transmitting requires a license."
Real-World Application
You can use any receiver (even a scanner or SDR) to tune to a satellite's beacon frequency and receive telemetry, even without an amateur radio license. The telemetry is an open transmission. However, if you want to transmit to the satellite (use the transponder), you need an amateur radio license. Receiving is always open; transmitting requires authorization.
Key Concepts
Why Other Options Are Wrong
Option B: Incorrect. While you need a license to transmit, you don't need a transmitter or special certification just to receive telemetry. Receiving is open to anyone.
Option C: Incorrect. You don't need certification from protocol developers to receive telemetry. Receiving is unrestricted.
Option D: Incorrect. You don't need to register with AMSAT or get access codes to receive telemetry. Receiving is open to the public.
