Two basic questions about satellite communication

Click For Summary
SUMMARY

Gateway stations, also known as teleports, are essential for spot beam satellite systems, as they facilitate communication between user terminals, which cannot connect directly. The discussion confirms that satellite beacons, such as those from Avcom, are utilized in various applications, although the extent of their use in operational systems remains unclear. Future satellite internet constellations are expected to enable direct communication between user terminals, marking a significant advancement in satellite communication technology.

PREREQUISITES
  • Understanding of satellite communication systems
  • Familiarity with gateway stations and teleports
  • Knowledge of spot beam technology
  • Awareness of satellite beacon functionality
NEXT STEPS
  • Research the role of gateway stations in satellite communication

Hi,

1. Is it correct that gateway stations (or teleports?) must be used for spot beam satellite systems? That means, two user terminals cannot communicate directly with each other.

2. Are satellite beacons widely used?

I'm not aware of operational systems where user terminals can communicate directly with each other via satellite, but the upcoming satellite internet constellations (here is a thread) plan this.
 
Due to the constant never ending supply of "cool stuff" happening in Aerospace these days I'm creating this thread to consolidate posts every time something new comes along. Please feel free to add random information if its relevant. So to start things off here is the SpaceX Dragon launch coming up shortly, I'll be following up afterwards to see how it all goes. :smile: https://blogs.nasa.gov/spacex/
