ITU-R P.525
ITU-R P.525 is a technical guideline that helps people measure the strength of radio signals that come from satellites in space. It's kind of like using a ruler to measure how long something is, but instead of measuring length, we're measuring radio signals.
Imagine you're playing a game of telephone with your friends, but instead of whispering to each other, you're sending messages with radios. The strength of your message, or how well your friends can hear you, depends on how close you all are to each other, as well as other factors like a noisy environment.
Similarly, when a satellite sends a message down to earth, the strength of the signal depends on how far away the satellite is from the receiver on the ground, and other factors that can weaken or strengthen the signal.
ITU-R P.525 helps people understand how to measure these signals accurately, so that they can communicate with the satellite and use its data without any problems. It's like having a manual that helps you use a radio correctly, so that you can hear your favorite songs without any static or interference.
