Episode notes
Why LEO Satellites Now?
- Traditional geostationary satellites had high latency, making real-time communication difficult.
- LEO satellites, mass-produced and closer to Earth, offer lower latency and higher speeds.
Ground Stations and Antennas
- LEO satellite systems require ground stations to connect to the terrestrial internet.
- Electronically steered antennas track multiple, fast-moving satellites for seamless connectivity.
Laser Links and Remote Connectivity
- Laser links between satellites (inter-links) enable connectivity in remote areas without ground stations.
- Starlink already uses this technology, providing internet access in Antarctica and Northern Canada.
